I recently purchased one of these head units from China. I like it. It is snappy and works well. After purchasing item, the seller contacted me and said that I needed to pay another 20USD for reprogramming, because of the kind of A/C in my Ram 1500. OK.. I found it odd, but accepted it.
When the unit arrived and I installed it, I was slightly disappointed.

I was hoping that the software would be tailored to the vehicle. Instead I'm getting these generic images showing when the car door is open and the image of what looks like an Aston Martin. I asked the seller if these can be changed and he said No.
I happen to know that the answer is false as if I would have bought the unit from Phoenix or Linkswell, I would have this..
Clearly that is a Ram.. and the other icons in the youtube video were also correct.
Anyone here knows how to change the vehicle icons?
Also, the reversing camera seems to be of a very low resolution compared to the crystal clear image I used to get with my factory 8" display. Would appreciate help in that area.
I'm not completely upset. These aren't deal breakers in me using the unit. I just wished for a little bit more attention to detail.
Is there anyone that can help me with getting my head unit to appear more factory?
1. I would like to change the vehicle icons to show the Ram or at least a truck.
2. I would like to get the camera to be more clearer.
3. Maybe change the theme a little.
Well...
The car pictures are included in the firmware and you can´t change that yourself without rooting the device, searching for the system apps which includes the different car pictures, creating your own pictures in the same shape, size and so on and put them back into the apps. You need to have a good knowledge of PSP to position and move the own pictures to the same view as the given one.
You probably need a couple of days to get that working and not look crappy.
Example: You need to create pictures for each door opening, you need to have pictures for all of them of the car from the exact same angle and this is needed for all pictures you want to exchange. Nearly not possible.
The cam picture is related to your camera. Seems that it is not of a good quality with low resolution.
Theme changes... forget it. No chance.

Thank you for the reply. It sounds like a mission to root the device and change the icons, but I guess vendors like Phoenix and Linkswell have multiple employees that can do that easily.
As for the cam picture, on my stock 8" factory Uconnect, it was really clear. Only after switching to the android unit, is the picture quite a low resolution. It is still usable though.
These vendors don´t do anything.
The software development is outsourced to another company and they just work on requirements. To adapt a software to your specific car... costs a lot of money, because the graphics need to be taken and worked on... Even don´t think about the possibility to get this changed by the vendor.
If you want to get it... you need to do it yourself. I started a while ago with it and gave up after some days because I did not get the relevant pictures in the right angle.
Ah one thing additional: You are not able to update your unit afterwards, otherwise all your changes are lost.
Example: Only for the door thingi, you need to create these new files:
@knightjp You will find these and all the others in the launcher.apk.
The files I showed are in \res\drawable-w720dp-hdpi-v13, but you need to look first if one change in there changes anything on your radio. Not a fast thing... and you need to use the radio on bench instead in car, because you need a long time.
@rigattoni Thank you for the information. How do you access launcher.apk?

Just use 7zip and unzip the apk on the desktop to work on it.
Attention: You need to exchange the files in the zip file itself (APK is just the same as a zip file).

Thank you for the info. I mean where would I find the launcher.apk so that I can make a copy of it to a USB and then work on it. I'm browsing through the file manager on my unit and I can't seem to find it.
Sorry.. I'm new all of this..
This are the details of my unit. I did manage to find a group on Facebook where one guy said that he could help. But then he said that my unit is a 1600x1200 resolution display and he doesn't have the custom firmware ready for these units yet.

I've checked with Linkswell. They said that the firmware only matches the radios they sell. Not sure I believe them since their radios are made in the same factory that mine was. They just put their own firmware on it.
Its fine. This group on Facebook have custom firmware that look really good and pretty much factory.

@knightjp
These units are too different as it would be possible to flash something from another supplier.
If you would have a MTC* unit it would be easy to exchange between different suppliers, but not for these units.
I even would not rely on any facebook groups... Too much idiots running around there. If you want to change something which is not done by the supplier, just do it yourself. You just need to make sure that you are able to reset the stuff if somethings going wrong.
Even to flash any firmware provided by someone else should only be done if the original firmware is available for getting the radio back working. Don´t use any firmware without having the original firmware.
@rigattoni I completely understand what you are saying. However this group came highly recommended by a number of forums, threads posts; specific to my vehicle and others. The users who have received custom firmwares from the group and are completely happy. They actually say that it is in many ways better than the stock.
Considering I have no experience with "rooting", etc., I don't want to do anything that will completely ruin the device unless I have clear instructions, step by step. I like the unit and it works well, despite the little things that make my OCD flare up.
So I will just wait.

I go fully with Marchnz.
At least if you not really know what you are doing and make an own question mark behind each instruction, you should not change anything yourself. Keep it as is and be lucky with the performance. Those small things like a different car on the screen... well... You loose more if you brick the unit.
The problem is, that this firmware needs to be made for your paricular head unit involving the MCU and built in hardware and not just for a specific car. Wrong firmware can brick the unit and if you are not able to help yourself out of this dilemma... you would be lost, because none of the current user would be able to explain the unit specific way to get out of this issue.
So I would say: If you don´t know out of memory to root this device and don´t have the original MCU and firmware... kepp your fingers away from the internals.... just some famous 2 cent.

This thread is dedicated to discussion, research and mods for the JAX SLX7786 Head Unit range.
What is it?
The JAX SLX7786 is a series of touchscreen Android 4.4 head unit. The most common size reported is 10.1", although 9" models have been seen in the wild.
The common characteristics of these head units are:
Specifications
OS Android 4.4.4
CPU RK3188 series (PX3)
Cores 4 cores
MHz 1.6GHz
RAM series DDR3
RAM capacity 1G
ROM series iNand Flash
ROM capacity 16G
Double SD card/MuIti-Media Maximum capacity: 64G
Screen Size Different Car DVD model different size (Edit: this particular one is 10.2")
Screen Resolution 1024*600
Screen Panel CTP (Capacity Touch Panel)
GPS module GPS/Beidou
WIFI Built-in(IEEE 802.1 lb/g/n)
3G Unicom/Telecom/Moblie(Adapter)
USB(Port) 3 pieces USB2.0(Extensible)
SD card slot 2 pieces
Moblie HD Support FAT/NTFS
Who makes them?
Good question. As far as I can gather it's a similar arrangement to the MTCB units; a number of manufacturers sell the unit based off of a central reference design. Who makes the reference design, and therefore who holds the kernel source, I do not know.
How can I get one?
The main place I have seen these for sale has been Aliexpress; most of the 10.1" units on the market seem to be this particular unit/ROM. The only other 10.1" units on the market (as far as I'm aware) are Joying units and pretty clearly marked as such.
The only surefire way to make sure it is a SLX7786 unit is to get the seller to send you a photo or screenshot of the build number under the System -> About page and check whether it matches the build mentioned below.
I think I already have one. How can I tell?
The easiest way to tell is looking at the System -> About page on the unit. If your build number contains the following then you have a SLX7786 unit:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
JAX or 885 as first three characters, and
Contains WQ-16EN
The full details of the build number are as follows:
[VENDOR]-[YY][MM][DD][HH][MM][0G]-WQ-16EN-[CARMAKE]
Where:
[VENDOR] = JAX or 885. Unsure why this changes from unit to unit, assuming different vendors.
[YY] = Build year, [MM] = build month and so on.
[0G] = String may or may not appear depending on model
[WQ] = Assuming this is OEM, like KLD and JY is for MTCB units
[16] = Not sure
[EN] = English ROM
[CARMAKE] = M6 for Mazda 6, ACCORD8 for Honda Accord, etc
How can I help XDA development?
Ask the seller for the most recent update, citing the bugs listed below. Share link with me via PM, or upload to Google Drive and PM me the link.

Music player: Yes, although you can't use steering wheel controls to skip tracks. I'm using Poweramp.
Home screen: yes, just install another launcher and it will ask you if you want to change launchers the first time you press home. Select the one you downloaded and click "always". Personally I'm using Car Launcher Pro and it works fantastic (and has on screen music controls) although it's a paid app. See the picture of my setup for a preview.
Hey i would like to add some technical issues i have with this rom.
1.)I like to confirm that you can not use the back and forward track buttons on other apps than the stock app provided.
2.) Under the car settings jax menu, entering the password 1234 grants you access to additional features. My gain controls in these menu do nothing. Bluetooth source isn't any louder, aux etc when adjusted.
3.)Was not able to change the default music app with a skin version or anything. (tried to remove via root, the installed a musicskin.apk in the system folder.
4.) Steering wheel controls is buggy, had to fiddle with it on different days until all the buttons are map, then no problem
5.)Viper4Android does not work with the stock apps (radio,bt, music, video). Works on some apps when i first installed it, reinstall doesn't work on some. Buggy
1.) Was able to root with KingRoot.

Hi bro,
I have solution for Audio output issue...
Today I found the solution, so no need to root anything.
While Mapping the steering controls., don't map -Vol.
Now my Audio output is same as my Original Car stereo.
Reason : I will post a video for this issue, because I cannot explain here...

Just a small update...
I've managed to extract my stock ROM from my unit using the Partition Backup tool by Wanam listed in the OP. I plan on uploading the dump, as well as the two other firmwares collected to date, to AndroidFileHost as soon as I get developer status approved there.
Also I have added some tools to extract the firmware to post #2. The Rockchip drivers are fairly useless at the moment as we don't know how to connect to ADB, Fastboot or U-Boot (the bootloader), but the RK3xxx tools are what I'm using to work these ROMs. Again, as you need to be a member at 4PDA to download these (which is a pain to obtain) I will upload them to AndroidFileHost at the same time.
At some point this weekend I'll be doing a 3-way diff on the firmware we have so far to assess whether they are homogenous, i.e. can be flashed to any unit. I have a feeling they are, other than the apks in /system/app.
If it is indeed the case I'll release a modded ROM with SuperSU and (hopefully) Xposed and Viper4Android preinstalled to kick us off with custom ROMs. My endgame here is to have a source built kernel and have the device booting CM13, but as I know 9/10 of sweet f*** all about programming in Java or building from source I'm hoping somebody with dev knowledge will be able to assist.
If not, I'd be willing to kick off a bounty to get a unit for a dev who knows what they are doing so we can get some up-to-date firmware on here.
Also I've noticed that @AbduL_PT may be able to port TWRP to the device; he has already ported it to a number of other RK3188 devices so he may be able to do this one. @AbduL_PT if you're still around give us a yell
Let me know what you guys think.
For those of you that are considering purchasing one of these units, they are now AU$363 (15%) off on Aliexpress from this particular seller for 11/11 day. If you're in Australia you can also use CashRewards for another 11.11% off.
Just bought another one for my partners' Mazda 6. Yes, our family has two Mazda 6s :laugh: mine is the Mazdaspeed6/Mazda 6 MPS though.

Kyle you are the man! Keep up the good work! :good::good::good::good::good:
I gotta read into backup the rom but then i can do it no problem.
I would like to note that i bought my unit a few weeks ago.
Also, i can listen to music while the gps app is open. Sygic, and iGo maps is what i used.
For those of you playing at home, I didn't realise that Xposed pre-Lollipop didn't require a flashable zip to install, as I only got into it with Marshmallow. Xposed installs fine on the unit with the installer from rovo's page.
I did play around with GravityBox [KK] shortly today, doesn't look like I can make the soft keys appear as I'd like though :crying: (as mine is installed in a RHD car the buttons are on the wrong side). Quite a lot of things actually do work though so it is running OK.

Thanks mate
I also bought my unit not that long ago - 23/10/2016 actually. Given my car is a little bit older maybe mine is old stock as they're not moving them as quick.
Updated third OP post with information on system.img.
The findings on this mean I can cook a custom ROM and anybody can flash it, provided they back up their /system/app folder before installing and restore it afterwards.
Hi,
Small update..!!
I tried to access seller's files.
But I'm not sure the file which are uploaded in the month November belongs to JAX SLX7786 or not.
Please check from your side.

UPDATE : The above firmware "4.4 885 B版 20161110.rar" has same GUI as I posted the below image, but this firmware is just a crap for my Honda Accord. Because I can see only Home Screen, nothing is responsive, it looks like Hang. I have tried to restart the Unit, but still nothing is working
This Firmware has different launcher, it includes Music player within the Home Screen. Also the music player is different.

You are a legend thanks!
I can see at least three packages there that are for the SLX7786 - 安卓4.4老马六专用软件.rar (which is for the Mazda "Horse" 6, my car), and all the ones for the Accords, which are for yours. The others I'm not sure of, I'll have to crack them open and have a look.
In case anybody else is planning on downloading these, you can download from Baidu without having an account by using this Tampermonkey/Greasemonkey script. I haven't been able to get our device added to AndroidFileHost yet, so I'll be uploading the files as soon as I do.
EDIT - After some poking around I think I've stumbled across a repository for these units. Most of the units are designatured 7706, not 7786. Even more interestingly, there seems to be some files marked with a "STM8" designation, as well as a project file. Looking it up, the STM8 is a microcontroller that can be programmed for MCU use. We might have MCU source here, but I'm not sure. Somebody better versed in microcontrollers would be able to tell.
I also found a file with an update for the ix35 which might help the Russians I linked in the previous thread.

Hi Kylemd,
Any update for the firmware which you have downloaded ?
Does it works with you ?
Hi everybody,
there are some new Android head units around with a bigger screen than the current double din ones. The resellers often calls them "Tesla Style Headunits". Sadly I've not found much information about it, yet. So I bought one on the SinglesDay in China via Taobao to check it out.
I already did a lot of research on the Internet about these things. But until now, I've not figured out who the actual manufacturer is. I think with these units it is the same like the MTCB/D, one manufacturer and lots of resellers. Here is a Link to a site that lists lot of theses units with the specs. But of course they are nearly the same. The only difference I saw was 1GB vs 2GB Ram and 16GB vs 32GB Rom. http://www.cusptech.com/index.php?c=products2
I tried to get to recovery mode, but no luck until now. But just in case something bricks while testing or to optimizing the Rom, it would be great to have the update.img. For that I contacted the reseller, but get the normal bla bla bla. Its stable (yes of course :silly and no updates are planned and so on.
On youku.com I've found a video, where someone did the update http://v.youku.com/v_show/id_XMTU5NjkwNDEyNA==.html. So it must be possible somehow. But my Chinese is not the best, so I can't contact that guy
So if anybody has more informations of any type about these units, would be great if he shares.
For anyone who want more informations, here is a review on YouTube in Russian https://www.youtube.com/watch?v=7Pa0T8AsY5k. If someone knows Russian, maybe he could contact iqnavi.
Thanks
i dont have any info, but i would like to see more units made for newer cars
There are some small updates.
First: Rooting via Kingroot is possible.
Second: I've managed to get the SystemApps and found the Bundle ID's com.choiceway for the launcher and com.szchoiceway for other apps like radio. But google it, did not bring any results
Further I was able to decompile the settings APK and extract all factory Pin codes. For now, I won't post it public, to keep the risk that the manufacturer maybe changes them, as low as possible. But if you are interested in them, you can PM me anytime. If interest is increasing, I will post them here of course.
Update 3
With the root I've found some config XML Files. The files are all called "customer_***.xml". There are 12 of them. I think they control the GUI for the different resellers. So I have merged all options into one XML-File and got all the GUIs available. The two "Customers" with the bigger XML-FIles are OCCAR (奥车凯) and Carcool (车酷时代). I don't know if they are manufactures or resellers, but my circuit board is also labeled with OCCAR, so I think they are manufacturers. Searching with the Chinese names I found the websites of these two. http://www.occar.cn and http://www.carcoolera.com / http://www.sz-carcool.com. I tryed to contact them via the WeChat App, but they did not response. Maybe they don't speak English.
Is there anybody here, who speaks Chinese and could contact them for me, please?
HI Airwin13!
I just ordered the same device for Ford Kuga 2014. I ordered it from other seller then you. Now DVD is on the way to me, but i got the firmware update.img from seller.
I have unpacked it with RKTOOLs and looked inside. Now there is 20 customers.xml files.
The first question is - can we add other languages then china and english?
Hi bonez,
thats awesome. One of the best news in 2017 until now Since the start of this thread and today, I contacted nearly 12 resellers and manufacturers, without any luck. Could you please upload the update.img somewhere for me? I also would like to inspect it. Maybe i can preroot it, so that Kingroot is not needed anymore. Did he also tell you how to get into the recovery mode?
So they managed to get 8 new Resellers. Lets see, maybe they also added some new Interfaces.
Adding languages should be possible i think. I decompiled some Apps Like the Launcher.apk and Navisettings.apk. These two are building the main GUI. And there are lot of strings to translate . Examples are at the Attachments. Then there are of course even more Apps like the Radio, Music, Movie and so on. So I think its possible, but means a lot of work.
I will send you a PM with the pin codes for the factory settings.
Great to finally see another user with these units :good:
Hi Airwin23.
I also purchased these Tesla Head units for my 2017 Toyota LC.
I too wanted to try and optimize these units as with 1GB ram things can get slow.
However I would like to note that out of the box my unit was already on version 5.1.1 however still shows up as KitKat ? It also has a date of 201612xx which is later? Hope this helps.
Also how did you root ? Really don't want to brick my new unit.
Also a interesting note is the ram mention 625/2G where on your screen shot shows 1GB. However when I look into running apps, my total ram is 1GB so not sure what is happening here.

These units use a Rockchip RK3188/PX3 which can take up to 2GB RAM. MTCB/C/D units also use this chipset and several of us in the MTCB forums have bought new RAM chips and upgraded to 2GB, from the pics it looks very likely that these units would take the same RAM modules.

you are right, 1GB of RAM is really not the optimum, 2GB would be way better. But I think typos1 is also right and an RAM upgrade should be possible. If you are interested in that, I can took a picture of the other side from the mainboard, there you can see the RAM.

I rooted with the Kingroot.app. But you should be careful with that, once rooted its very hard to get rid of the Kingroot App again. Factory reset does not help in this case.

I think you should trust the Android information screen. The YXZ/2G Info is, as far as i know until now, only a string inside the Navisettings.apk and outputs the info depending on the vendor set in the customer.xml. So I would say its fake and your unit also has 1GB of RAM. You could also check it with the CPU-Z App.

Spoke to the reseller. He mentioned they made the update to fix the issues with mirrorlink. Not sure about this as I could not get this working. Advisers to install MOB Interconnection service.??
Also how do I post the screen shots ? Usinf mobile version? Any other quick way?
Do you upgrade the Ram to 2GB?
So did the reseller send you an update file or it was already installed, when you bought the unit?
Sorry I don't know what the "MOB Interconnection service" is. But I did some research on Google. Looks like it's a Framework used by the Mirrorlink (EasyConnect) App. But I don't know, how to fix that.
That's a bit difficult, because the statusbar is hidden by these units. You could install an APP from the Playstore or just do it oldschool and took a picture with your smartphone
No, I'm still on 1GB. At the moment I don't have planed to upgrade.
I have two update files for these units. The units I ordered are 10.4" Vertical oriented for 2015 Mustangs. I was able to get the software from the supplier, and I would be happy to provide people with the files, but I'm not allowed to post links to my Google Drive or Dropbox.
Also, we have already extracted the img files and checked the build.prop and everything we could find, but I'm not savvy enough to know, is there a way to remove the password for advanced options on the unit, by using the img files?
Oh thats cool. Could you mybe send me the links via PM, then I can post them for you if you like.
Why would you like to remove them? I will send you the codes.

No came pre-installed. I asked for the update file but he didn't have it. I've got screen shots in the below link which I hope helps.

You mentioned that it will be different unrooting. Are you saying this will just take time or impossible? I want to disable allot of the programs to save Ram is that makes sense or is there a better way to do this?
Does anyone think they could find out what a PIN code is by having the source files of the image? I have tried all of the common ones, to no avail.

Rooting is possible via Kingroot, like I said. It's just hard to get rid of it again, if you don't trust the Developer of Kingroot for example or because of any other reason.
If you only want to save RAM and not Space on the ROM, then I would recommend to first try to uninstall or disable the unwanted apps via the settings menu. If you don't know how to do that, maybe this helps https://www.youtube.com/watch?v=puTFvKFNyH8

bad links
Sorry, my mistake. Please try again.
After spending time with those files this weekend, the first is just the 4.4.4 image that came on my unit, the 2nd file is the 5.1 upgrade. The downside is, they are designed around the Mustang, so it will have a Mustang-themed boot screen, as well as a Mustang in the launcher.
I am a noob to rooting, and flashing custom roms. However, I'm very computer literate.
I bought the Xperia X compact because it appeared flashing roms would be very possible.
I have a simply idea, I want to make a rom that is so ultra minimal many of you might think I'm crazy.
All I want it a phone with a black screen, one icon of each: phone, contacts, txt, calculator.
that is it. I don't want internet, I don't want GPS.. nothing. I don't want any trace of any company on my phone.
Think of it this way, I want a blank slate, like a new fresh computer, and I want to install the OS of my choice, with only the things I want. I can't seem to find anything like this(it may exist, but my searching of the web returns nothing close) Can someone please help me with this?
Thanks in advance.

install any OS you want, root, and delete system folders of whatever you don't want. Then, you can end up with a black screen and 4 apps and nothing else. However, there will never be 'no trace of any company' unless you build your own components and design your own os. Even the 4 apps you want are developed and installed by the os maker, and they run how they want tjem to, (including collecting data, etc). Also, removing apps is removing a small part of the system that runs the phone. There is the kernel, system processes, and more that are required to use the phone at all, (or even turn it on), and all of these things are designed to operate a certain way, and contain many traces of various companies. You can't remove those things.
But, if what you want is the appearance of such a thing, you can easily attain that.

Thanks for the reply,
I guess, what I'm asking, (maybe your answered this) is it possible to install the OS, and not install drivers to run things like WIFI, GPS. I simply have no use for them. I currently turn them off on my X compact. I can get two solid days without charging my phone with just these two things turned off. Second, I use nothing on the phone, but placing calls, occasional TXT, and simple calculations. IMO there's absolutely no reason to have anything else on a phone. so in your reply you say install the OS I want, root it, and delete anything I want. So, since I don't know much about this and I'm still learning, what are the most one can delete from the system and still have a functioning phone? Does Sony publish a list what's on the Mother board, and what drivers run them? If there is it would be a great starting point for me to get an idea of what can absolutely not be deleted.
Thanks again!

May be a list compiled somewhere, but I can't say I know enough about it to give you direction. I think it would definitely be a chore to figure out, since modern roms can have over 100 system apps installed, (between /system/app and /system/priv-app), plus all of the other stuff. As far as Sony publishing info, they have an 'open' program for developers, but it's not entirely open source. You can find all of the sources they do make available on Sony developer site.
Personally, I usually just use the built-in app disabler and disable anything I don't want, and it hides the icon. Some things you can't officially disable, but you can use a third-party app, or delete app folders, but you want to be careful and make a backup. Maybe just move folders to a temp folder somewhere, in recovery file manager, and see if it reboots. Then, if not, you can go back to recovery and put it back...

I know that Sony has their open environment for developers. I like that they do this, its a good thing. I think there is a forum on their, I might be able to get some answers. I thought that on XDA, someone would actually know what you can and can't delete since it appears to me, making a custom rom would require deleting and removing things or adding things. Someone probably knows... From my perspective, I have found that most things that reference custom ROMs (here on XDA, or YouTube) seem to revolve around, either tricking out a phone, or "I did it! because I can"... "this does not work, I'm going to figure this out" and all of that is very cool. but I have not seen much in regards to hacks that make phones more useful, like a tool instead of the toys they are.
when I find out anything from Sony or on my own about doing what I propose, I will post back here. If anyone has any ideas or resources just let me know.
Thanks!
I think you could probably do better with some classic phone (not smartphone) with requirements like this.
A Sonim XP5 would come closest to fitting your requirements right out of the box. You start hacking on a smartphone too much and you'll end up with a paper weight.
The sonim xp5 looks promising.
I ordered a used from ebay I'm going to give it a try.
I still think phones should be sold with an option to Install anything you want just like computers. In fact the Industry would be even better if they followed what computers did. Allow people to purchase their own Mother boards, enclosures, batteries, and components, and let users build their own phones. just think it would a much better market.
Thanks for the help
got the XP5 but its not what I want either
The XP5 is ok.... If I want to survive a nuclear holocaust! That thing is thick as brick. Its a neat idea, but a little to limited.
OK, so I'm thinking has anyone installed a straight Linux OS on the Compact.
any thoughts?

yes. Linux deploy works great. I had Ubuntu and Kali running smoothly. Look up a tutorial, but know that there are a few ways to do it. I used boot-from-sdcard method . Basically partition sdcard, using 8gb or so of ext4 for Linux, then open Linux deploy app, and set preferences for environment, then install os, (takes a while and you need a strong internet connection), then use vnc app to connect to the Linux desktop. Almost everything works well, but sound is tricky. I got it partially working with media server app. Also, the file system is set up slightly different than on a Linux computer, so i had a little trouble with apktool... Another nice thing about it is that you can easily mount your android storage to the Linux desktop in terminal, and the Linux os runs basically as an app, so you can just go back and forth on the fly, and transfer files easily.

Hi Guys!
My new android head unit has a very ugly and poor designed software for using while driving, so I'm already thinking about trying a custom firmware or return it and be back to my stereo + cellphone + BT.
Maybe if I list my issues if you can tell me if a custom rom can solve my problems.
If I can't solve it, maybe it can be useful for developers.
1- Sound switching: Some apps like the FM radio do not pause when another app try to use the audio output, so if a want to run, for example, the Deezer, I have to stop the radio first and only after that I can play the music. (could not find another good radio app)
It is not only annoying, but it is kinda dangerous to look soo much to the screen while driving. In the ideal scenario, when I choose the source using the steering wheel control, the chosen app will play in it last state (the music play keep playing the last song, the radio play the last station etc).
2- Automation: For example, in my original stereo, if I remove the USB stick while playing it will go back to the radio or bluetooth and keep playing music. And if I insert it again, it will detect that is the same USB stick and start to play from the same music again.
3- Steering wheel button mapping: Some apps (mostly the radio again) do not respond to the same logic as the others softwares, so, if I press the pause button, mostly apps will stop/pause playing, but the radio will try to find the next station.
Another problem is that the unit wheel software do not map long pressing the keys, so the numbers of commands are very limited.
4- Fast and accurate volume control: That problem is addressed by the Agama launcher using a gesture on the central ring on the main screen and it works very well, almost like a physical button. But again I could not use the Agama as my solution cause I cannot use the steering wheel control to change the source. In the Agama, If I press the source button to go the bluetooth receiver or the radio, it will stay on the app screen and I have to press the home button to have the main screen again.
If you made it until here, LOL, I think it may work something like this:
- You could choose the main apps to be selected by the source button (kinda like it is now, but you can choose how many sources you have).
- In the SWC (steering wheel control) some buttons would be global and others could be send to the application on the source "slot". Long pressing mapping too.
- Some commands of the SWC could change depending on the chosen source, so it can be more useful in different apps.
- Automation: if you are stopped, you can use the apps and the screen as a normal tablet, but if you reach a chosen speed, the unit will go to the home screen and the apps will run in second plane, unless it is in the list of apps that can stay on the main screen while moving (custom).
- Widgets to control radio and music apps could share the same area on main screen and will be show depending on the source choose.
- When moving, the main screen could priorize gestures to control main functions like volume and screen brightness or turn screen off. The gesture priority could stay on until the first single touch gesture. If you are stopped, the first single touch will enable the "tablet mode" again to permit full use of the unit. The gesture priority would be back as soon you reach the set speed again.
Hope it can be useful. =)
Better you return it. ;-)

Sorry to say, but Torsten is right.
Nevertheless... You even did not tell anything about your unit.
What make, which MCU and of course the current used firmware.
May be one would be able to give some answers...

Sorry, I did read the rules, but when I was trying other launchers, the unit stopped to show the screen after the google logo.
At the time I started to write that giant message I was waiting to the seller to send me the recovery files/procedures, so I would be able look at the MCU model and put it in the specific forum. Happen that he did not sent it yet and I could do it. =)
If I can use your patience for one last question before the weekend, can I run those ROMs in virtual machines to see how they work? I do not have much time to decide to return it, so I'm trying to make the best use of this time.
It is 2-din 9 inches generic capacitive buttons unit with automatic Android Auto and Carplay. (2g+32g 4 cores uis8141 CPU). It has a very good screen, it is very fluida and looks amazing in the car. My main problem it is not drive friendly.
I'm not that laze guy. I did watch and read tons of reviews in forums before decide to buy and honestly, I was not expecting to looking for a custom rom so soon, cause nobody tells how it is not drive friendly. To me, I would only change the launcher for a better looking one.
Another option would be keeping it as a learn lesson and join the development group to try yo make my own mods.
Thank you for any extra help!

There is unfortunately no single custom ROM for these UIS8141.
There are 2-3 other threads talking about these units, but that´s it. Just search in this forum for UIS8141.
By the way... Even if you find any other firmware for these units, I would not recommend to use it. You need to give the Chinese guys at least some time to answer. They start working at least 6hrs earlier (for Europe) and leave work 4-6 hrs earlier than we do.
Wait until Monday and send a reminder early in the morning, that your unit has stopped working.

I hope you've written them a short, simple and easy to understand message. Often enough their answers doesn't fit to the question.

There is unfortunately no single custom ROM for these UIS8141.
There are 2-3 other threads talking about these units, but that´s it. Just search in this forum for UIS8141.
By the way... Even if you find any other firmware for these units, I would not recommend to use it. You need to give the Chinese guys at least some time to answer. They start working at least 6hrs earlier (for Europe) and leave work 4-6 hrs earlier than we do.
Wait until Monday and send a reminder early in the morning, that your unit has stopped working.

Thank you! They send me file to reload the firmware using an USB stick and it is working again.
I was think all those Chinese tablet style units had similar software, like the cellphones works, but the Android is very modified. Next time I will try to buy one with a more popular CPU and firmware.
I do realize if I use the original launcher and apps and change only the standard navigation app it works fine, with a very limited interface in terms of customization and information, but works.
The most interesting part (in a bad way) is the system does not allow android widgets to work, so any launcher like Vivid that uses widgets to do custom screens are useless.
I also kinda make it work using the Agama launcher and the NavRadio to control the radio but still a not so fluid experience. The original is "better".
Thank you anyway, you did help a lot.

It is a good tip. I'm not having problem to talk to the Chineses on AliExpress. They just answer only on question per day. LOL
Since this seller in specific sells a lot of these units, I was expecting a better custom service, but it is very crude. No site, no online detailed user manuals... they did send me a very poor quality video on youtube to show how to force the USB upgrade. The seller store is LEHX.
Thank you for the help!

Same problem with other sellers. The Chinese support is very weak and they don't know much about the devices they are selling. Especially if the question is not standard you often get no valuable answer.

You may try Fcc Car Launcher. This is a widget based launcher and works with a lot of different CPU combination.
By the way:
Exactly this is the reason I buy from Klyde.
I can get in contact with Klyde via WeChat and if I have something special, I have a direct connection to the developer and get information or new firmware within 1-2 days.
I don´t buy this kind of things on AliExpress. I never did that and I won´t do that at all. Cheap small things for some bucks... okay, but nothing over $100.

Me too. I think was the first time I bough something over $50 on Aliexpress. Here in Brazil, if you buy anything under $50 for personal use you do not need to pay import fees.
About the Fcc Car Launcher, I did realize the unit are not allowing widgets from any source to be installed, so none of those nice Launchers work as intended.
But it is getting better. The radio integration is better using the NavRadio app from here and now I'm trying to work around the widget problem.
Found some users here that are unlocking the widgets installation on the Amazon Fire Tablet using the ADB and the config files looks identical to mine. If I can find a USB drive that works, maybe I can make the widigets work and make it look a little better.
After the initial frustration, I'm kinda enjoying tinkering with it. Still not sure if I will install it cause I'm very serious about security while driving.
Thank you again. Regards!
By the way, the only reason I'm insisting on it is cause I think it fits very well on my car (a mk2 Ford Focus) and since it has native Carplay, maybe it will be not so bad to use. We will see...

So I got this thing from Amazon there's like 300 bucks on sale so it's worth a little bit more than that which from my experience with previous PX3 px5 systems usually if you spend a little bit more you get a better quality product. But this one doesn't seem to be an mtcb or an MTC I can't really figure out which head unit it is. It says it came with Android 12 and a octa core processor. Also says it has 6 GB of RAM and 128 GB of storage. It looks very similar to my old dasaita hu. It says the processor is a b200 and I've never even heard of that although it said it came within AC8*** processor here's a screenshot of the setting screen if you guys could help me identify so I can find a custom rom and get some information on what I can do with this thing that would be cool. Thank you.

It's an STM32 type device.
Awesome. Thanks.

Yeah I'm very aware of what the search function is. I just wasn't sure which terms I should be using to search, hence me asking.

Hence providing the search terms in addition to answering your question which was so graciously gratified. I could have remarked without remiss for a post in the wrong forum, including a software development forum for what might be considered a request for others to do leg work
You really don't want a custom rom and they do not exist. Even the MTCD hacks are just modded factory ROMS which largely fix problems.
Suggest relegating the STM32 to experience and replacing with an UIS7862 FYT based unit. Don't take it personally, the forum is littered with posts from those that buy first and then read the forums second to resolve issues or determine what would have been better. Could also be an opportunity to start a new thread in the correct (Android head-units) forum and start (limited) development for this odd ball.
Not (MTCD) requested moderator move to (Android head-units) forum
Yeah you make a really good point. I didn't think it was going to be that hard to find information on this thing. It'd be cool to have a modded ROM for this particular device as it's not necessarily slow. It just needs some love a little fine-tuning and probably a smack across the face. Haha. Yeah I may look into just selling it and getting another one. Thanks for your input I appreciate it

It looks like I just fell into the same hole! Very similar firmware - STM32 - 20220607-11-BD3-57 but mine also says it's a B100 4 core 32gb/2gb and is running android 12 (supposedly - can't be sure based on others comments of the os/cpu, etc. being faked!) - Only just fitted a few days ago and it's working ok with the navigation software included / plexamp / reversing camera. I'm not too worried about customising the rom in this case but the issues I've had so far:
Google apps all run VERY slow - google maps virtually unuseable, play store is terribly slow to download anything.
Bluetooth to ODB2 adapter won't connect no matter how I try
Can't change the start logo as with other models
Under the Factory settings menu you can log on with code 8888 OR 6666 - using 6666 there is an extra menu item of 'Settings Item Hiding' - I'm guessing that maybe further options for setting up ODB2 might be hidden in there but I can't figure out what the code might be!!

Yeah I've been using Aurora store instead of the Google Play store and I found it more than adequate. I stopped using the play store whenever I could. Plus because it's a stereo other people can get into your car or borrow it I don't like being signed into a Gmail account or any sort of personal data being left on there so what I did is kind of a hybrid method. I use Aurora store for all my Google Play needs I just don't sign into Google Play or Gmail or anything and then I use an account that I made just for my car to like get notifications or at the very least be able to sign into things with Google like Spotify and still be able to have like a playlist personalized and all that but not leave any of my personal account data at risk.
But yeah Google Play store Google maps all of its completely unreliable and unusual so I just went in and disabled Google Play store and I'm probably just going to disable Google Play services as well because it's ****ing useless. Unless one of the other frameworks like a minified open source version or implementation of GSF you know just me better success I'm not really sure what else to do. Switching to another browser will help for your browsing needs so instead of chrome I haven't checked to see if chromium is available for Android but I know Firefox works great so I may switch to that. I'm still in the process of setting mine up. I think when I get some down time later on tonight I'm going to actually try and pull apart the wrong and see what kind of fixes or tweaks I can apply to it. Who knows maybe I can at least get the ball rolling on some sort of development for it and then some of the old hands can come in here then show us how it's done. Maybe if somebody show some actual effort into making these particular units worth modifying as far as their software goes other people will start doing it cuz the processor itself shows promise and it's definitely not slow. I mean in any benchmark that I've seen the AC8257 is ranked in like the top three I guess a lot of the rockchips soc.
And yeah I just actually got into that menu earlier and it doesn't open up much it does give you some engineering tools to modify the camera and the radio a bit. I mean other than it being slow for Google services and not being able to change the default launcher very well or customize how it looks I mean it's doing its job it's just in some aspects it's lacking. I'm hoping I can change that so I don't have to go just flat out by another head unit.
