Hotaudio Model 2100: 2DIN 7" 1024x600 RK3066 Android 4.4.4

Hi Guys,
I've been searching but couldn't find info on this head unit. It looks like they upgraded the screen to 7" 1024x600 on an older dual core 1.6Ghz RK3066 to make a universal 2DIN unit. It seems to be a recently released model, looks like a nice unit for a good value.
Does anyone have this HU or know about it? Hotaudio seems to be the original manufacturer, is there a better known clone of this unit?
All I can find searching for "Hotaudio 2100" are some posts on a Russian forum:

Any info or ideas?

Hi. This Hotaudio RK3066 - 1024X600 HU is considered a HuiFei type, so check out the thread below for more info:

Here's another thread on this specific HA HU that could help too:

Also, below's a link to Malaysk's Custom Rk3066 - 1024X600 ROM Images that have worked well for me with this HU:

My opinion of this HA HU is that it's inexpensively made and not perfect. For example, I had to relocate the WiFi antenna out the back, as the factory location inside of the unit created a very weak signal. To clarify, moving the antenna lead out the back of the unit increased throughput up and down by at least 10x + on my unit. Moreover, my HA HU also has an input switching issue with my vehicle's factory amp that creates a single loud popping sound through the speakers when switching from music to radio inputs or when turning the vehicle off. That said, this issue was not present at all with a prior Winmark Android HU in the same vehicle. I even installed a RCA ground loop isolator - noise filter and made sure the ground was to chassis, but the input switching loud single popping sound is still a problem with this HU. I'm guessing it's an issue with how crudely this HU the switches power, which is unlike the soft power switch and volume ramp up of my last Android HU.
Another issue with many of these Android type head units including this one is the boot up time. It's at least 20-30 seconds, but you can set the HU shut down time delay up to two hours. Still, it's not equal to having an any time almost instant on HU like my last one.
All the above said, this HU is decent if you can find it for around $200 US, but I'd recommend going with something of higher quality if cost is not a big concern, or at the least look for one of these units or similar ones with the quad core RK3188 processor and good support.
Bottom line is that these units are inexpensively made IMHO, but they can be fun to work with; thanks to Malaysk and all the excellent XDA developers and contributors. Plus, I still have not found any higher quality brand names to date that run pure android, OBD2, and have as many other app options available.
Best to all,

Thanks a lot for your informative post rhacy.
My unit just came in and I was wondering if this was the WiFi antenna you relocated out the back?
There seems to be an adhesive copper antenna tab taped to the inside of the chassis near the screen at the front of the unit. If you route it out the back wouldn't it put the antenna further away from the seats where you'd want the stronger WiFi signal? Was the stock placement of your antenna the same way?
Your previous Winmark HU with the instant boot up time was a Windows CE unit with Android running in a VM, or was it pure Android? I've seen the option in xdAuto firmware for the Carpad HUs to set sleep delay for 1day, 2days so it will instantly boot as long you drive every few days. I wonder if we can do that on these HuiFei units somehow?
I've seen mention in the changelog of an adapter that addresses factory amp pop by introducing a delay before switching the input, at least during turn-on. Maybe using an adapter like this might address the issue?

Do you have Steering Wheel Controls working with your unit? Does your vehicle have resistive controls or canbus?
I'm going to hook mine up to power and test it out, will report any issues to this thread. Anyone who has one of these Hotaudio model 2100 please post your experience.

Hi rcll,
Your more than welcome and thank you for the heads up and link for an adapter that addresses factory amp pop by introducing a delay before switching the inputs, at least at amp turn on. Cheers!
Here's a link to one I found on ebay that looks like it may work in some instances:
http://www.ebay.com/itm/PAC-TR-4-Ca...gger-Module-/191226517960?hash=item2c85fd19c8
Moreover, I'll do some more research and try to find an adapter that can sense any input switch and soft switch the amp. Well... I will if the new Android HU I just purchased has the same single loud popping sound when switching inputs or turning off. The new HU is a Joying JY-UQ124 Quad Core RK3188 1024*600 16GB 2 DIN system. It was purchased because I missed having an actual volume knob and wanted to upgrade to a quad core as well as see if it would fix the loud single pop sound issue.
Please note that I have emailed Hotaudio multiple times over the last month or so about the loud single pop sound issue when switching audio inputs etc., and Summer has stated that they are working on the problem and will send me a fix if and when they figure it out.
Also, if it helps at all, the Hotaudio HU is installed currently in a 2003 Mitsubishi Montero Limited with the factory infinity amp, 6 speakers, and a Polk sub-woofer. It's a non CANbus and non SWC SUV. As I mentioned in my previous post, there were zero single loud popping noise issues with the Winmark Android HU that I installed in the Montero prior this HA HU. The Winmark has a gentle audio input switching and a nice soft volume ramp up on any input including the radio. It was listed as a Pure Android Single DIN HU with the pop out 7" 1024x600 display and it has worked well. I only replaced it because I did not like how far it stuck out of the dash even with the display in. Plus, the display had to pop out in order for me to see my reverse camera or access my nav apps and that got old real fast. Also, I was concerned that the display motor or its ribbon cable would fail eventually.
Here's a link to Winmark Pure Android 4.1 Single DIN HU:
http://www.alibaba.com/product-detail/Pure-Android-4-1-universal-1_60150935774.html
To clarify further, the Winmark Pure Android HU is instant on when using the android music player or radio, but it does take 10 seconds for the display to pop out and up. That said, I'm guessing that there must be a sleep or standby mode for the Mstar system that Rockchip does not deploy. Plus, I know for sure that the Mstar system does not need to boot up even when the Montero has sat for days or weeks without use.
In regard to the Hotaudio WiFi Antenna, yes, mine was in the exact same spot originally. However, mine did not come with an adhesive copper antenna tab at the end of the antenna lead on the side of the case. It was just soldered to the inside sidewall of case. Your unit may perform better with the copper tab, although, I think there will still be more interference due to the antenna lead being inside the case. On mine, the difference between the factory mounting location and the lead being routed out the back (through the rear mounting bracket hole and then attached to center upper rear housing screw) has been a massive improvement in both signal strength and throughput. If I was not pressed for time during the antenna fix, I would have taken pictures as well as mounted a RP-SMA Antenna on the back housing like the one in the link below.

http://www.ebay.com/itm/171505160014?_trksid=p2055119.m1438.l2649&ssPageName=STRK:MEBIDX:IT
Further, I did ask Hotaudio for help with the ridiculously weak wifi signal and directly related low throughput issue, but they only suggested using a USB WiFi adapter instead of the internal WiFi radio. D'oh! And even then, there was no information on which adapter would work, or how to set it up, where to get the drivers, or where to get it. In turn, I pulled the HU, relocated the antenna lead, and tried to explain to them the poor factory antenna location problem. This was more than a month ago, so hopefully they are doing a better job on new units. Please note, my Winmark HU has the WiFi antenna routed out the back and it works great. Also, the forthcoming Joying HU routes the antenna out the back too, so hopefully it will work great as well. Anyway, if you're bench testing your HU prior to install, you can at least test the signal strength and throughput and compare it to your phone etc., and then decide if you need to reroute or not. Although, if you like to connect to home or work WiFi networks, I'd recommend relocating and upgrading the antenna.
Yikes... my apologies for type rambling...

Did you ever solve the popping sound before you switched to the Joying? This is my second HotAudio unit, my first one had a power issue. They sent me a new one at no cost, but this has the speaker popping as you described. My first one did not have this issue. And no word from Summer yet. I really don't want to go through the hassle of shipping this one back and waiting another 2 weeks for a new one. Frustrating.

Hi vdubskey,
No... I haven't solved the Hotaudio single loud popping sound when switching audio inputs or turning off yet. On an encouraging note, Summer sent me a link to new ROM and MCU images yesterday should fix the single loud audio popping sound. I'm guessing the fix is in updated MCU audio switching assembly code, but I've already installed the Joying HU and it's been working great for the most part. To clarify, out of the box the Joying HU has zero audio pop issues, decent WiFi throughput, and is obviously faster due to the quad core. The only issue with it so far is low mic volume and some background buzzing noise for the person on the receiving end of my Bluetooth paired phone calls. D'oh! There always seems to be some issue with these head units.
Anyway, if Summer has not sent you the download link to the New4_rk3066_h(20150831) ROM & MCU images yet, you can pm me for the link. Please note that I'm going to email Summer and will post the link and password here if she gives me permission to do so.
Best to all,

I also bought this model and with the latest files from Summer, I noticed that the input pop sounds went away : ). Super happy about that
It is too bad I have to stick with the files from HotAudio/Summer so I won't have the popping sounds. This also means I won't be able to install the Malaysk's current custom rom as you will hear the popping sounds

I have this same HU and it has been nothing short of perfect for me. Try and update the MCU to the new (20150831) HA file and then put in Malaysk's ROM. The popping sound should be MCU related not ROM so you shouldn't have any problems.
I personally haven't updated my MCU yet so I still have that popping sounds, only the ROM to Malaysk's Aug24-2015 and it's running flawless. I bearly notice the pop anyways.

Great news. She just sent me a link with a firmware date of 09/09/2015 so hopefully it fixes it. Yea I appreciate all the work Malaysk has done but all of the UI changes done are not to my taste. The stock firmware looks much better IMO. I just extract the stock firmware images and rebuild with the modded apps I use and use then flash and apply *#hct#root# to root and install xposed and get the same experience with the same look as stock. Works for me [emoji6]

Summer at Hotaudio has given me permission to post the links below that should fix the single loud audio pop when switching inputs or when turning off.
Please note that these ROM Firmware images should be for 1024x600 Hotaudio Dual Core RK3066 & Quad Core RK3188 Head Units, but I haven't testing them yet, so use at your own risk.

Yup that's the firmware I downloaded, the 9/8/15 one. I upgraded to a quadcore SOM for this radio. I'll try the MCU image first and see if it solves my problem and then the UPDATE image if I need to. Should get these posted to the HuiFei file server as well. At least the MCU files anyways.

Thanks! Please let us know if the single loud audio pop goes away or not. Also, once you flash the MCU, could you post the MCU version number for the new RK3188 MCU from your Settings - about section?
Moreover, once I know the both the new HA RK3066 and RK3188 MCU version numbers, I'll see if I or someone can post them to the HuiFei and mega.nz file servers - ( https://mega.nz/#F!KMZnXTJC!zDFMlP4qgxEE6vQxt8rrrw ), or if you do, please let us know.
Thanks again.

The MCU that was included in the 3188 download is v2.73. And that is what my system already had prior. I am still getting the pop randomly when switching music and radio apps. Although I haven't got the pop on boot or shutdown yet except a very tiny one that might have been related to something else. I'll have to do some more testing.

Hey guys, I am a total noob when it comes to dealing with these android head units. I am wondering if anyone can tell me if there is any way to have music (I.e. Mp3, radio, or other sources) to play continually, or at least while I am in the Nav app. Riding in silence just to use the Nav is not cool....

Yikes! I updated to MCU 2.73 on my HA rk3066 about month ago and still had the single loud audio pop when switching inputs or turning off. Regardless, thanks for posting the MCU version. It's probably a waste of time, but I'll bench flash the MCU included with latest rk3066 ROM from Summer to see if it's newer than 2.73.

Try going into Settings > GPS and selecting Mixing. There, you can also adjust the volume settings between your music and gps voice directions. Please note that this GPS volume setting may not work if you're using a GPS app with text to speech street names.
Hope this helps...

Hey can you post the version number of the MCU that took the pop away. Also the firmware date? Is your unit a dual core or quadcore. Thanks.

Update: I went ahead and flashed the update.img after the MCU.img had no effect and it has resolved the speaker popping. So it turns out the even tho the MCU probably does handle the input switching, it must have been how the OS handled the execution. No facts to back that up but just my opinion. Now I have to mod this version all over again and setup my apps but oh well.

Thanks for posting that the latest Update Image from Summer at Hotaudio fixes the audio pop. I did bench load the included MCU for the HA rk3066. Unfortunately, it was version 2.60, so I knew it would not help. Thanks again for verifying the fix is the new firmware.
Cheers,

Another update: So the newest firmware fixes the pop when switching from radio to music and vice versa perfectly. Haven't had a pop yet. But I'm still getting a random pop here and there on ignition off. So I think I'm going to going to wire my DCDC-USB power supply in-between the unit and the battery so I can use the power off delay function to make sure my amp is powered off before the unit so I don't get the pop. Hopefully it works out.

Does anyone know how to get into recovery mode? This model doesn't have physical buttons but it still has the reset button. I tried going from maylask's to the original img. After flashing, it never booted successfully and now I'm stuck on the android logo screen. Any pointers ?

GA5151F Manuals?

I recently installed the GA5151F in my 2007 mazdaspeed. I do did not get any manuals for it. They gave me a link for a website manual but that unit was not listed. Does anyone have those? I contacted Eonon too and if I get them I will post them here.
I am also wondering if I can use the Malaysk rom with this unit and if so is there a guide to doing it? I have been searching and reading but not quite sure exactly what I need. The info for this seems to be all over the place or else I am just not seeing it. I have rooted and flashed android devices before. Thank you for all and any help.

I have the same unit in my Mazda3 with no manuals. Didn't really ever need it though since there was an installation video. What exactly are you looking for with the manual?

I wasn't looking for anything specific, just wanted to look it over to see if I was missing anything important. Did you modify yours with a different rom or anything?

Not yet. I've actually been looking over a lot of sources to see what changes I can make. Malaysk ROM looks like it should be good as long as you use the ones for RK3188 / 800 x 480 resolution. That can be found here: http://forum.xda-developers.com/showthread.php?t=3246370. Information and instructions on where I found that it works is here: http://forum.xda-developers.com/android-auto/android-head-units/eonon-ga5153f-mcu-t3217479/page2
It looks like changing the rom is fine as long as you don't make any changes to the MCU because i don't find any support for MTCB-ZD.
You can also find other useful apps and information at the following link that are applicable to most android units:

Thanks a lot for the info, I may just mess with it this weekend. I will keep you posted.

HU Updated
I got a little bored last night and decided to go through with this.
I put the update_4_4_4_FUSE_800X480_RK3188_16_MAL_22_05_2016_AUDIO on my head unit and it worked.
I put update.img on the root of a usb stick and put it in the port labeled usb.
I turned on the unit and went into the Settings menu, move to very bottom of the menu, select “About tablet”
Select “System Updates”

Select “Wipe data from the flash” option and click “Install”
I then let it fully install and it sat at the mazda logo forever. I finally read more of the instructions and saw it will always do that.
I shut the car off.
I then turned the car back on holding the power button and I pushed the reset button, not sure which one did it but then it showed it was erasing
After that it booted up and everything worked well.
My only issue is that the Android Head Unit app service thing does not control google music, which is the only music app I really want to use.
Any ideas?
Also is there a guide for this rom and all the cool features it has?
I also don't understand how I stop the radio when I switch to another app like google music? It keeps playing unless I hit the mode button and switch to music.
Another problem I would like to address is when my phone connects over bluetooth for it to auto turn on wifi tether, I think tasker can do this but I wasn't sure if there was another app. I do really like this head unit but I have a lot of tweaking to do before I get it where I would like it.

Thanks for the info. Should be useful when I get to it so I don't freak out from the logo.
For Google Play Music: http://forum.xda-developers.com/showthread.php?p=63877529 . I think this app just had a checkbutton for me to use spotify, but it should support google play although I'm not sure if you need to do anything extra.
Malaysk guide: I am not aware of any, but it seems to be used across a lot of head units so there is probably some videos on YouTube.
Radio issue: I think it may be a bug in Eonon's MCU which is only updated by Eonon and you probably have to specifically ask them for any updates. I may do that at some point because it annoys me also. I usually was just exiting out using the back button before I found that mode fixes it temporarily just recently. You might be able to just use Tasker to kill the radio app whenever Google Play Music is opened.
Auto-tether: I used tasker to do this whenever it connects to EONON on bluetooth and would automatically end the tether when disconnected. Other apps may work such as https://play.google.com/store/apps/details?id=eu.inrete.autotethering&hl=en
As for me, I used to have my unit set up where tasker on the phone would turn on hotspot and use spotify through the head unit. Now, I just have my HU start up at bluetooth and tasker on my phone opens a specific spotify playlist whenever it detects i am connected to Eonon. I mainly do this just because I download songs on spotify and podcasts to my phone whenever I'm on wifi to save data. I'm thinking about mirroring my phone using EasyConnected and seeing how that works out on the HU.

Yeah, the last pic was.
You have an MTCB units made by ZD.
There are some manuals around, come KLD ROMs have them on the unit, you dont really need one, but if you must one have I could get a copy for you, its not very detailed and its the same for all units from all manufacturers apart from minor details like the launcher.

Does that microphone mod still apply to these units? I have not had a chance to test the external mic but it is all hooked up. Another thing I was wondering is if you still need to do the audio mod to get better sound quality on these units as well. I won't be taking it apart any time soon but when I upgrade to an amp and better speakers I might if that is still needed. I also can not figure out how to get the screensaver mph to display anything and the clock is wrong. Thanks for the help.

The ZD units are relatively rare, I think youd have to take yours apart to see about the mic set up, but its probably roughly the same as the other units, which are all slightly different but they all need modding, best check out the mic mod thread to see if anyone has done it to a ZD unit.
Pretty certain it will have he audio controller hooked up to the MCU rather than Android so you would need to do 7floor's audio mod, assuming of course that youre not happy with the sound as it is, there is a slight sound quality improvement with the Lollipop update so you may wanna try that.
What screensaver is that, one from on here or did it come on the unit ?

It looks like changing the rom is fine as long as you don't make any changes to the MCU because i don't find any support for MTCB-ZD.

Its not that the MCU is not suported, its that the ZD units have only started appearing recently so they are no MCU updates yet, plus you cant get a copy of the MCU off the unit, in time ZD MCU updates will no doubt turn up.

Radio issue: I think it may be a bug in Eonon's MCU which is only updated by Eonon and you probably have to specifically ask them for any updates. I may do that at some point because it annoys me also. I usually was just exiting out using the back button before I found that mode fixes it temporarily just recently. You might be able to just use Tasker to kill the radio app whenever Google Play Music is opened.
Auto-tether: I used tasker to do this whenever it connects to EONON on bluetooth and would automatically end the tether when disconnected. Other apps may work such as https://play.google.com/store/apps/details?id=eu.inrete.autotethering&hl=en

These units need an app to control switching between music apps other than the MTC ones that they come with, otherwise your ll get 2 sources playing at once, this is what @JohnnyTightlips was referring to.
Eonon are sellers ONLY, all they do is buy these from ZD, stick badges on and sell them, they do not make the MCU or have anything to do with it, its a ZD MCU ie, like all the other MTCB units, its an STMicroElectronics MCU with software developed by MTC for ZD. Its not an Eonon MCU, the radio issue he was talking about is the one I referred to above.
Forget about Eonon (apart from as a possible source of updates) and about "GA5151F" (it means nothing), you both have ZD MTCB head units - a good example is if you bought a BMW from a dealers called Smith & Son, you dont have a car called a Smiths & Son, you have a BMW.

My next and previous track steering wheel controls don't seem to work in Google play music. I see the next and previous toast come up on the screen when I press them but nothing happens in the app. volume and mute work great. I'm not sure if maybe there is a setting I'm missing. I also don't know what the control settings app does. And in the viper audio tool what settings do I adjust for Android music apps? Also what is the biggest fat32 SD card I can have in each slot 128gb? Thanks for the help.

Isn't the mic mod just for units that only have internal mics? The HU already has the option for an external microphone so I don't see much reason needed to solder in an external mic. Nobody that's called me has complained of the internal mic so I haven't even connected an external yet, but I might next time I take it out because it's too annoying to put back in.

I have the external mic hooked up and did a test the other day. I was driving at 80mph and the person on the other line said I sounded great and it sounded like I was using the phone itself. My external is mounted to the top/side of the steering column.

Control settings is for CAN Bus data, different apps will appear depending on what setting you have your unit set on in factory settings.

All units have built in mics, most people find it useless for calls but some find it ok for google now.

Does that canbus app let you do anything? I opened it and it have a bunch of buttons but nothing seemed to do anything. Is that where I am supposed to set what the steering controls do?

Xtrons PCD760LOA-B Looking To Hide Status Bar

I bought this unit for the family Zafira B. It fits in lovely and I have no issues with any of it. Well, almost. One thing I hate is the status bar, which on this thing isn't small. It's pretty much constantly there, including on every GPS app I've tried. As well as being annoying and taking up far too much space, it's going to eventually result in a pretty bad case of burn in.
So, in short, I want rid of it unless I swipe down to show it, in other words I want to run immersive mode at all times. However, Xtrons don't seem to happy about making this easy. I have tried every app that should allow it but it would appear the writing of secure settings is something they have either disabled or it's not there in the first place. I have tried to root with KingRoot to no avail, it fails on 70% every time. I'm not bothered about root that much, I was only trying because it's likely it would allow me to get rid of the status bar.
Any suggestions as to what I can do at this point would be appreciated.

Processor Type - QuadCore-R16
Android Version - 6.0.1

Hi
Sorry I don't know the answer to your question but I stumbled upon this topic when searching. I am looking to replace the HU on my Zafira B and the Xtrons HUs keep popping up as they are specifically made to be compatible with Vauxhalls and come with the CANbus box so steering wheel controls work etc. The only thing that is putting me off is that all listings on ebay and Amazon and on Xtrons website say not compatible with Zafira B with on board computer. I just wonder if this is actually the case. I know that you will lose the computer button whilst installing an aftermarket stereo and that setting the clock and date can be a problem afterwards but other than that, do you find it a problem? Do you lose things like fuel consumption and fuel info from the top display or is there a way to still display them using steering wheel buttons?
I'd be interested in your thoughts as the Xtrons units seem good value.
Many thanks

Does this help?

Dasaita 10.2" head unit visualizer and other quirks

Hello, everyone.
I bought a Dasaita 10.2" Android head unit for my Jeep about a year ago. Love the Android functionality. However, it's got some quirks. I am hoping someone can give me some guidance on them.
I'll start with (hopefully) the simplest:
1) Visualizers don't ever work. That's unfortunate, but such a large head unit with a nice screen. Is there a setting somewhere that might make them work?
2) Sometimes when I first start the vehicle, the default (and crappy) mp3 player starts up automatically. I never use it, but can't uninstall it. There must be a hidden setting somewhere that tells the unit to start this app, but I can't find it.
3) Someone said I could view the backup camera even when not backing up. I changed the settings like another thread said, or I thought I did, but I never get any video from the backup camera unless I'm actually in reverse.
4) Only about 3 times now, it has frozen when I back up, and when I am moving forward again, it still shows the last view, a frozen snapshot, from the backup camera. No controls work. It must be restarted to get that camera view off the screen.
5) I see firmware updates on XDA, but am not sure how to tell which one is for my device. I can't post a link to the one I bought from Amazon, but the description says this: "Dasaita 10.2 inch Large Screen Unviersal Double Din Car GPS Stereo 4G+32G OCTA-Core Chip For Jeep Wrangler 2015 2016 2017 With Blutooth Wifi Car Audio 8G Meomery Card"
6) 3 USB connectors, but only 1 seems to work. When I asked support about it, Quick said to use the one that works because it is "more stable." Is there another purpose for the other two?
7) I didn't use the external mic for Bluetooth, and although Bluetooth works and I can hear people fine, people complain every conversation that they can't hear me. Even if I'm sitting parked. I finally gave up on Bluetooth. Is the included mic a lot better? Apparently it's unusable for me as-is.
Overall, I love the functionality and can't imagine going back to a standard head unit. Would like to just fix these quirks. If you have a fix for any of them, please let me know!
Thanks,
Brian

Help with Android Head Unit install in 2013 Audi Q5 (p60? Android 10?) (backup camera, mmi controls, air bag light)

Hello, I hope this is the right place, I keep finding this forum every time I search trying to trouble shoot my issues. Long story short, I had been eyeing these head units for my Q5 to add CarPlay, a local installer recommended the same model, and I thought great, so I ordered it and they installed it. I am however having 3 issues, and while the seller has been helpful, they are on a completely different time zone and it’s not progressing well unfortunately. The installer can’t find anything wrong. Little did I know what I was getting into, and I can’t find a manual or even a specific model number to search on.
My Car:
2013 Audi Q5 MMI (3g, gps nav, etc built in, AMI port in glove box, but everything else is in the center console under the screen)
Unit I installed as recommended by installer:

My 3 issues:
1) My OEM backup camera does not show video. The radar sensors work. When I put the car into reverse the unit changes to backup mode, but the video image is black. There are multiple backup camera options in the software, I have tried them all. The after market selections at least give me the radar visual and lane lines, but still no video feed. The OEM option only shows me a black screen with a picture of a Q5 on the right.
2) The audio from the head unit is not coming through the car stereo. None of the center console controls work. The right 2 control buttons around the knob are both always flashing slowly. Only Radio works and can be controlled by steering wheel. My phone seems to be synced to car‘s original Bluetooth, and audio takes over when I get a call.
3) My airbag light in the dash is on. I am certain this is because the bezel they sent me only has the hazard light switch.
The unit otherwise is getting better and better as I learn to use it and CarPlay, which I ultimately bought it for, is working well too. My wife and I though are really struggling without the backup camera, and I fear I’ll be ripping the whole thing out and putting the original unit back in if I can’t fix that.
I have pictures of everything inside and out I can share. I’ll add them later as I can. But since this forum keeps coming up in my searches, I thought I would get a conversation started and see if anyone could help me. Really appreciate any assistance in advance. At this point I’ve become versed in taking the car apart and can get behind the entire vertical stack in the center and have confirmed what I can. I’m pretty handy with software as well.
(At the very least to start, a picture of my backup camera options in the software, I’ve tried them all)

Sorry to say, issue 1 and 3 are quite sure installation issues.
For the first one: Quite clear and could be measured: The backup camera has no power. There should be a connector for the power feed. --> instructions.
Third one: They removed the connector for the airbag, while checking the unit with ignition on. Can be reset at the dealer or by someone who has the right tooling.
Second one: Look into the settings of the unit and check the settings for the CAN box. 2 possibilities here: You got the wrong CAN box or the setting is not set to external amplifier.

@rigattoni thank you

Well installation issues, at this point I think I can fix (famous last words). Getting parts / seems to be harder with communication challenges. (was instructions supposed to be a link?)
I pulled things out last night, I didn't find the RCA yellow video in I expected (there are 2 but they both seemed to be for aftermarket and are disconnected. There wasn't the obvious yellow <-> yellow rca adapters I see everyone else have with the power feed to the reverse lights. I'm assuming it's (in theory) feeding in through the primary adapter (block of plugs) going in to the back of the Android unit. I was able to account for all other connectins.

No link, the seller should at least provide some installation instruction with the unit.
As I don´t know the unit and don´t know what has been provided with the unit itself, I am not able to help.
Your backup camera should have a video output which needs to get connected with the head unit. Where to put, needs to get from the seller. If he is not able... send this crap back.
The same for the airbag error message... If the seller is not able to give clear instruction... send the crap back.

Seller finally agreed they didn't send me all the right cables. Specifically they mentioned I need an AMI cable, but also the LVDS plug (in the photo above, in the top left) ... should have an adapter. Which I've specifically asked them about a few times in pictures, but as I suspected it, it can't just be unplugged and needs an adapter to plug into the rest. So... those are on their way, we'll see. I suspect the OEM backup cam video comes in via that cable based on my research and wiring diagrams, but again, we'll see.

Good to know.
Did they give you a guide how to fix the airbag issue?
Just to let you know: In case of an accident, the airbags can be activated or not without control. This is a severe security issue, you should take care of.
The AMI cable just provides audio and is normally used for external audio sources like iPod, IPhone and such things. May be they use it to get the head unit speaking to your OEM amplifier. I don´t know your unit and the specs. At least Audi is not that easy with these kind of units.

Well, predictably, nothing's easy.
They sent me a splitter cable for the airbag (passenger occupancy light) and hazard button. (but there's only one input to split into ....
LVDS cable was missing, so that connects the LVDS feed -> back of android. I do finally have some sight to the OEM UI, but only briefly, and I can't interact with it with any buttons. The backup camera will come on but only briefly, and only the first time. After that it cuts to OEM nav, and then only for a second.
AMI adapter (straightforard) would in theory help audi, but I suspect the priori issue with the oem system and lack of mmi buttons working is somehow blocking control / and thus "aux" audio.
However, at the least, I was able to remove the OEM occupancy / hazazrd button, and attach it to the splitter they gave me. Tucked it into the dash (meaning I can't... see the light but for now fine) and cleared the Air bag code. And yes, air bag stays off. Finally. So that's better.
I'm awaiting their reply on all the rest. Driving me crazy. Based on searches, I'm starting to wonder if this is programmed for the wrong baud rate? I only vaguely know these terms, but have stumbled across similar symptoms of people retrofitting MMI 3G+ and issues witht the controls not working, flashing red lights.

Hello where did you put the splitter into?
1 goes to the original cable
1 goes to the new framepanel (without the air bag light)
and where goes the third cable?
Please help thx
