New 4.4.2 Kitkat Head Unit (Newsmy Carpad NU3001)

I'm updating this post so as to provide an overview of what is discussed in the thread (and in hopes that people will quit asking the same questions over and over that have already been answered).
There is a ton of great information in the wiki here. Please read through it before asking questions here - this thread has gotten very, very (very) long and it's tough to keep up with what's happening when people keep asking questions that are in the wiki.
The below info is from November; current info is in the wiki.
WHAT IS IT: The Newsmy Carpad NU3001 is a dual-DIN Android head unit that runs KitKat 4.4.2, has a 7-inch screen, and no physical controls. It's nice-looking, very well made, and comes rooted out of the box. The manufacturer seems to be quite responsive to bug reports and feature requests, releasing frequent ROM and MCU updates to fix problems and usability issues. Oh, and we have full source code.

MAJOR FEATURES:
Quad-core 1.6GHz Rockchip RK3188 CPU and 1GB RAM
FM radio (RDS currently not working, awaiting a software update, priusfan figured out how to hack station names if you really must)
8GB Flash
Android Box that contains CPU and most of the Android guts connected via cable that can be unplugged and removed from the car
Built-in Wifi
1024x600 Capacitive Screen
Dual Bluetooth: one is standard Android BT for use with ODB etc. The second is hard-wired to the phone app and only works for phone calls and streaming music.
Pure Android, no fugly launchers, minimal other apps that aren't bad.
4x25W amplifier
WHERE TO BUY: http://www.aliexpress.com/item/News...eral-Android-only-without-DVD/2035002543.html COST USD$339. People are reporting various delivery times, mine shipped next day and arrived a week later. Note: this is the actual manufacturer on AliExpress, other pages are resellers. Do with that what you will. There is a dealer in Spain if you'd prefer to buy from Europe, it's 417€ plus shipping with VAT included. http://exclusivecarauto.com/android-quadcore-carpad-wifi-p-1001.html
BASIC Q&A:
Is it any good? Yes, it seems to be stable and work as expected
Is there a version for my car? No. It's only a universal 2-DIN package
But I saw one for a... No, you didn't. That's a Windows CE/Android frankestein thing made by the same company. You don't want it.
Does it work with Torque? Yes.
Does it work with my SWC? Supposedly, nobody has tried it yet. There is both CAN bus and resistive connections.
Can I talk on the phone and use Torque at the same time? Yes.
Can it be rooted? It comes rooted out of the box.
What ports does it have? USB Host, USB OTG, little bitty HDMI for when you take the Android Box out of your car and hook it to a TV
What connections does it have for my car? 4 channel high-power speakers, FM antenna, 1 set of line outs, 1 set of line ins, 3 composite video ins, CAN bus low and high (confusingly labeled + and -) and the usual complement of battery, acc, ground, dash lights, reverse switch, etc.
Does it run ....? Yes, think of it as a 7-inch tablet with built-in amp and radio that looks great in your dash.
AliExpress? Yes. It's like the Chinese eBay. Buying from them is not complicated. Summer, the girl who handles orders, is responsive and helpful.

CAVEATS:
There are no balance or fader controls, no equalizer, etc. You get 25 watts to 4 speakers and a single line out to hook up your subs or amps or whatever. Fixed in firmware 1.0.9
RDS doesn't work at the moment, they say a software update is in the works.
The microphone input is hard-wired to the phone-specific BT module. This means among other things that you cannot use Google Now voice control with this unit until we figure out how to connect a mic to it. There is plenty of USB connectivity, so it's only a matter of time. USB microphone works, including "OK Google". http://forum.xda-developers.com/showpost.php?p=56386685&postcount=359
OTHER INTERESTING THINGS:
There are extra wires in the AV harness that are for old-school steering wheel keys that use a resistive matrix. It ought to be possible to hook up all sorts of buttons and controls in a car for various stuff. The MCU is aware of these.
It sounds really good.
Screen is bright and crisp.
Using the Android box with your TV requires a DC adapter that is not included and nobody knows what the specs are. It's 5V DC, appears chargers from old Nokia phones with the teeny tiny plug will work
I'll try to keep this post updated but it's my busy season at work so don't have a lot of time.
Here's the original post that started it all:
I've been wanting to buy a H/U for a while now but nobody makes one of the Huifei ones for my Saab 9-3, and the universal ones are so gaudy and fugly that I've just kept searching, hoping to find something better looking. Today I came across this Italian guy on eBay, selling a very attractive universal double DIN with Kitkat. The one he's selling is a dual Android/WinCE unit (not interested) and claims to have both an 8-inch and 10.2-inch screen, so not really trustworthy.
BUT. I did a reverse image search on all the stuff he copy/pasted in the wrong aspect ratio and came up with a different model from Newsmy which claims to have a quad core A9 @ 1.6Ghz and be pure Android 4.4.2 with no WinCE.
Other stuff:
- Works with steering wheel controls
- 7" display @ 1024x600
- NO optical drive
- Dual bluetooth (one standard BC5 for the phone, one for OBD).
- Good TDA7851 amplifier (28Wx4)
- All the usual crap like car DVR, TV, etc.
- Screenshot shows a stock launcher, no sign of any UI that looks like it's from an 80's sci-fi movie.
- I am aware that it appears to be a cheap tablet stuck to the front of a 2-DIN chassis
- No line outs that I can see, one of the sockets on the back is labled AV IN and looks to have a lot of pins, and another that seems to be a firewire port labeled Key Accessory Interface. No idea.
The only way to buy one seems to be either for USD$299 through a reseller on Aliexpress, whose listing is mostly incomprehensible, or direct from Newsmy on EC21 for USD$200. I have no experience with either site.
I guess I'm going to roll the dice and see if I can get one of these shipped to me and find out if it's any good.
ETA: found a ton of pictures; apparently you can pull the front panel off and connect it to your TV via HDMI.
EATA: not allowed to post links so you'll have to Google I guess.

did you find any news about this carpad?

What are the pros nd cons to use a HU with android and winCE?
Is there a reason why to use winCE instead of a Pure android HU?

Pure Android HUs have to cold boot each time the car is turned on (I don't understand this, certainly a tablet with a battery in airplane mode could last for many days without affecting the battery of a car, so I don't get why a HU can't be left in this state vs completely shut down) and startup time is way too long. The WinCE units are set up that way because they actually run Android in a virtual machine on CE and just suspend the VM when the HU is powered off. CE can start up in a couple of seconds and so your time to operation of Android is a fraction of cold booting every time. This sounds like a mess to me and I'm really only interested in a pure Android HU. From what I understand the Chinese companies have engineers working overtime to reduce Android boot time and some have it down into the 15-second range.
N.b., I've been unable to buy the one mentioned in the original post. Both websites are broken and companies don't responde to mail.

Thank you for your reply.
Thats a big disadvantage of the NU3001 and what about the DT2001S-H-H?
both are android 4.4 but the DT2001S has 2gb ddr3 + Wince

I'm curious
I would like to know more about this head unit. Mostly is it reliable and how does it look in person. Does anyone have this yet?
Thanks,
Brett

Nope. Im a littlr nervous to biy with such little info on it.

I'm ordering one direct from Newsmy right now on Aliexpress. We've been exchanging messages for two days trying to make sure their canbus adapter works in my car. Hopefully I'll have it soon.

Sweet. I guess you're braver than me. Do you have any idea how long till you get it?
---------- Post added at 10:59 AM ---------- Previous post was at 10:55 AM ----------
Were you able to get any info about subwoofer connections? My car has a factory sub and I couldn't find how you would tie it in. The seller told me it is connected through a "voice output cable". Do you know what that means?
It seems like a pretty nice unit from specs. It's the reliability that concerns me the most -- with no online reviews to be found. I am also a little concerned about that touchscreen volume control. Seems like it could be a PITA.
thanks for sharing.

Which car you own. I am looking for a solution to my Skoda Yeti 2013. I had a chineese WinCE unit from the local dealer but I have returned it as the FM receiver was super crappy and the BT hands free worked only half of the time.
The issue still open for me is the quality of the FM radio although one can use the Android H/W to listen to radio through the internet. Not sure how fast would that change stations.
I was looking the Mistui FM receivers but I am not sure what is the exact model and thus that is the sensitivity.
Some Mistui receivers are pretty good ones.
All solutions that are not original VW do not have any support the the dual antenna with the built in diversity control. On the other hand most of the cards do not have such an implementation and radio still works fine.

yes. That's another concern of mine -- radio reception. Seems like it should be the simplest part, but I am constantly hearing about poor radios on these units.

Well, it's ordered. I opted for the 3-day SHL shipping and then noticed after I had paid them that "processing time" is 30 days.
The whole thing stinks like a scam, but I guess we'll see. It'll either be here in a week or in five weeks.

I just noticed that the aliexpress add says this: "Newsmy android 4.4 quad core car dvd 7 inch for univeral Android only (without DVD, bluetooth,NU3001)" Do you think that means that it doesn't have bluetooth? Surely not.
Also it looks to me like the guaranteed delivery time is 30 days. I bet you'll get it much quicker than that if you chose DHL.

2-din HeadUnit Quad Core Brand Newsmy 4.4.2

Hello all,
I have been searching for a good head unit radio for my car since july, and never been able to find a good one that I can ben sure of what I am ordering.
ker2gsr from here got me a link from Newsmy : NewsMy head unit thatlook pretty good on first look.
I contacted the company and here is what they said: "First of all, let me introduce our brand to you. We have our own brand"Newsmy", China top 10 car dvd brand. All our products are made by our factory. We are factory.
And we have our own technology, all our products are made by our own R&D technology.
Since you know: Roadmaster, Huifei, Klyde, i think you well know this industry in China. Are you a seller in Canada?
Actually a lot of factories in China dont have their own technology, they just use software company's solution. So it is very easy for them to produce product, they just need to assemble all the parts and became a product."
If they really are the factory, might be easy to maintain a good rooting project !

And the android box ! I do not know what to think about it .....
I find it weird when I read that it can support android 5.0 ... but it might means they will continue the update for a while !!
Here are the specs:
Do you guys think we should jump on these unit and try rooting them ?
Thank you very much,
Martin L.

So how much have they quoted you for

It is at a very decent price !
The only thing i am worried about is that, after asking questions, she finally said it is a android box! !
Just a screen with an android box that i can install somewhere in my car.
It is firewire port so i can bring it home and plug it to my tv... something I'll never do.
So two things have to be known nor. .. are they rootable, and is it a good thing having it in a box instead of direct in the head unit ???
I will post photo of the box tomorrow.

I added the android box picture on the first page , I do not know what to think about it !

Talk source code with them that's usally a good indication of they know what they talking about it if its just a sells pitch

When I received the email regarding the android box, I answered with a question:
"I see there is other plugs behind the head unit (speakers, antenna, ect). So there should have something installed in the head unit as an OS.
How does the head unit antenna send the signal to the android box's radio app ?
Is it windows CE in the head unit, or any other OS ?"
She did not answer that one, might not be real "pure android" ...
I can easly buy a sample headunit with 7" screen and plug in a chrome cast ...

Yeah see that's the problem with these so called factories is that they are not .they have good sales pitch but then when you get into the technical they have no answers that's why I've been reluctant to pick up one of those Chinese units

This link does not work anymore !
but I am afraid of ordering from ebay, we have no idea what we are buying !
That is way I am searching for a good companie that I can order from knowing what we buy !!

I've come to this one as well on aliexpress.
Thanks to you i've realized it is a capacitive display + an android box plugged in.
at this point, it would be cheaper to buy a nice display and plug a chromecast to it., i believe.
plus, instead of buying from china , i could simply buy in EU and avoid import fees and have warranty in addition

you're right!
how dumb of me not thinking of that.
anyway there is still a way to bypass that issue: plug mobile phone with jack audio to the navi system (jack cable works as antenna for the radio on the mobile phone).
but of course, that's not a nice solution i'd like to have in my nissan juke !
so, i've just ocme up with another idea: chromecast + pioneer appradio . what do you think?

[SOLVED] How to use Steering Wheel Controls (SWC) with Zlink/Zbox/Spotify/Apple Music

[SOLUTION]
This integration is not present on most head units so I wrote a Xposed module which hooks the proprietary button press handling methods and translates them into standard HID keypresses. This means that SWC will work with Zlink/Zbox and it will also work with other apps on the head unit such as Spotify and Apple Music.
See https://forum.xda-developers.com/showpost.php?p=79312591&postcount=56 for the first release and follow the thread for later releases.
Note that there are two types of releases, final and debug releases. Final releases do not display and debug information via toast messages on the screen. Debug releases display button press information via toast messages on the screen which allow users to collect this information and submit it on this thread so that it can be integrated into the module and their buttons can be supported.
[ORIGINAL PROBLEM]
Hi all,
I recently just picked up a Witson W2-W329 unit. Basically it's a PX5 unit with the following OS Build and firmware:
CPU: ARM Cortex-A53 eight-core 2+32 GB PX5; CPU: PowerVR G6110
Build: PX5-userdebug 8.0.0 OPR5.170623.007 eng.bsp.20180528.174007 test-keys
MCU: 2018-04-16 17:04:06 ZHAN_(NOR)__90_C9RD6686_CAN(A)PX5D1804160
After some fiddling with USB ports I managed to get CarPlay working and to be honest the interface makes the unit feel premium vs the standard bluetooth audio interface. I'd love to use it over the standard interface BUT.... steering wheel controls don't work.
I've got it installed into a Renault Koleos which has a CANBus box. So here is my question...
Has anyone else used CarPlay on a PX5 unit and been able to use their steering wheel controls with it?
It would seem as if the OS just has to push the commands through to the app via some sort of an API. The kind of integration you would expect...

Are you using the zlink app for Carplay or do you have a dongle?

Zlink. What Witson unit do you have? Is it PX5 and running CAN? Do you know if the SoM is made by FYT?

and has also firmware for my car, with can bus and the same px5, screen res & ram. (maybe also for your car)
what is different is that i have a built in dvd drive and the joying unit does not.
1. Is it a bad idea to try this firmware? joying has a newer firmware
2. is it possible to revert to the preinstalled firmware if it does not work properly (backup)?

I have the same problem, also with can bus with a w2 w207 wiston device for my peugeot 207
joying has similar looking mcu names
and has also firmware for my car, with can bus and the same px5, screen res & ram. (maybe also for your car)
what is different is that i have a built in dvd drive and the joying unit does not.
1. Is it a bad idea to try this firmware? joying has a newer firmware
2. is it possible to revert to the preinstalled firmware if it does not work properly (backup)?

A few thoughts:
Some weeks ago the user @walkin123 tried the same thing. He installed the latest Joying FW onto his Seicane unit. The unit accepted the firmware but knew that it was not a joying unit (they must have some sort of a handshake with the MCU) and therefore displayed a banner at the top of the screen indicating that the FW does not match the MCU. Even though his FW supported CAN it seems that it does not support all of the vehicles that the Seicane FW did and so he was unable to select his particular vehicle from the Android system. Even though Android does not perform the CAN decoding it seems as if it configures the MCU and possibly the CAN box as to what vehicle to decode for and without the option to select his vehicle he lost all CAN inputs including steering wheel commands. On the plus side the FW solved all of the other bugs that he was experiencing.
Another possible problem is that while the MCUs and the interconnections within the units are similar they are not identical. For instance they seem to use different radio tuner modules which the MCU controls via I2C/I2S. You may lose radio functionality if the different modules are not protocol compatible but you may be OK if they are.
Regarding the backup and restore option, this is something that I have been investigating for the last week. I believe that it should be simple to make a backup of the /system /restore /data and /misc partitions so that an Android restore should be possible. Whether or not the unit will allow you to force an older ROM over a newer ROM is something that I am unsure of. @surfer63 or another experienced member would be able to help you there. In the case of the MCU I also believe it is simple to extract the img but once again I am unsure of how simple it would be to write it back over whatever you install.
Perhaps @surfer63 or one of the more experienced guys could comment on this.

Ok, thnx for the explanation!
I'll probably wait/hunt for a more suitable firmware then.
I think the swc function for the zlink app is just something they forgot to implement, all other stock apps do have swc, so a small update would fix it.
I also noticed that the zlink software in my unit is 2.X. The latest from zjinnova is 4.X.

All the best getting firmware out of Witson. I think you would be the first person I have hear of as being successful in doing so. They have literally zero support. I would never suggest buying from them unless you absolutely have to. Joying support is FAR better.

I'm afraid you're right. i think i will try some retailers selling "s200" devices that claim they provide software updates.

Somone on this forum has extracted an updated version of the zlink apk from a joying firmware with build in carplay support. Could this solve the steering wheel problems? Is it possible to run the 2 apk’s with different version numbers side by side?

Just be sure you are not mixing the zBox APK with the zLink APK. If you did find an updated zLink APK I'd be interested to know where. I would like to give it a test.

On this site there are people who do get newer versions of certain s200 wxxx mcu’s from witson, So if a new version is released you will probably find it there first.

Sweet mother of pearl.......WITSON just contacted me with a firmware update dated 02.08.2018. After weeks and weeks of absolutely no feedback whatsoever they just dropped this one....
Will install it this weekend and see if it fixes the issue.

Nice!, Thats fresh from the oven. Is it specific for your car?:angel:

It's labelled as specific in the filename but when you scan through the MCU folder it has a list of compatibly radio and CAN configurations that seems to cover everything that they sell.

Dig through the archive and check what dates the files were modified on. Looks like they labelled it 02.08.2018 but to be honest there is not much in there that was modified after April.

I’ve installed it, and it is EXACTLY the same mcu number (same date, same time, same everything) as you described in the beginning of this topic. Nothing changed, zlink app still on 2.4

Exactly my point. Did you check the android build details and are they also the same?
Joying actually make improvements based on the problems that the customer is experiencing. WITSON stick their head in the sand and hope that the problem will disappear. I'm planning on doing a youtube review to show how poor the service is and how many bugs the unit has just to try and help other people. To be fair I will probably give it another month to see if they are actually interested in working on new firmware.

I did not check the Android build yet. A youtube review might be usefull, also for witson to see how they are screwing things up. I hope there will be custom/alternative roms available in the future, since it uses the same hardware as many other brands. I will try The zlink apk from Joying this weekend to see if it changes anything.

I know that gtxaspec is working on a custom ROM for FYT based PX5 units. He fried his FYT SoM though so I think he needs more time to get another. When that is ready it should be compatible with our units provided it does not touch the MCU. That being said I am not too familiar with all of the interfaces between SoM and motherboard and whether there are major differences in implementation between the two resellers. Could be that the Joying ROM (which gtxaspec) is basing his off does not have support for the CAN vehicles that we need...anyway we will see with time.
Let us know how the new zlink app works out.

[PX3/PX5/PX6] - Create Generic Android Car installation for all cars

Hello
I'm new to both the forum and the Android Auto section.
I acquired an Android system for my 2010 Volvo XC60 (without original multimedia equipment) on a well-known Chinese site, and after delivery, I encountered some problems on the interface part with the car (as much with the controls at flying than the air conditioning part): Nothing works. After a few exchanges with the seller, I was just able to get a partial refund.
But I wish I could have this fully functional system in my vehicle.
I have been looking for a solution to my needs for a few days, here and elsewhere.
And I realize that the installation in a Volvo is not supported by most PX3/PX5 supplier. The mechanical part is not compatible with Android 2 DIN autoradios.
So, after some research, I wonder if it is possible to leave on a motherboard basis PX3/PX5/PX6 depending on size or other, and to add a touch screen (in my case the one present on my Chinese system).
I had in mind - a motherboard based on RK3399 ("pcb pcba assembly custom solution RK3399 motherboard for vehicle" on Alibaba). But the question is how do I make the connection to CAN BUS and its decoding?
Do I have to put a set-top box? Is decoding done by the software part?
My idea is to make a system based on Android standards (9.0 preferably) that could finally fit into any vehicle (will remain as the mechanical installation part)
Could someone help me on this topic/this idea?

Google can really mess up a translation :laugh: So if I get this right you're saying the Steering Wheel Controls and the HVAC don't work and the Head Unit doesn't fit in a 2DIN opening.
The SWC and HVAC are controlled through the CAN Bus they should have supplied you with a box specific for your car. You can buy a box from somewhere else but it has to be made for your car and the HU has to have support for your car. The CANbus decoder talks to the HU through the MCU. That's a controller board inside the HU that interfaces the real world with Android (the SOM or what you call the motherboard). Yes there are 2 separate boards and they need to connect together can you see where that's going
The HU not fitting is hard to understand you're gonna have to explain that better or take some pictures.

Hello
Thank you for your reply: Indeed automatic translators often complicate things.
To return to my problem, there are actually two things or possibilities:
1. Run the kit I bought
2. Creating a new solution
My needs:
- An Android interface for my car (Volvo XC60 2010 without Sensus/Multimedia screen) with touch screen
- Have functional steering controls
- If possible performing (start-up and GPS)
Initial situation:
This not allow me to use standard 2 DIN HU
1. DO WORK THE KIT I BUY:
The kit in question:
there is a CANBUS case:
I think, like you, that the problem revolves around the decoding of CANBUS. But I don't know how to solve it or even analyze it.
2. MOUNT A NEW SOLUTION:
What I know I need:
Android motherboard (SOM)
CANBUS decoder
Screen (or use of the one I have)
The necessary connectors
But the I do not know what to take as SOM ... and where to find a CANBUS set-top box for my 2010 Volvo XC60?
I would like to build a solution not for my car, to allow other people to use it, by customing mecanical integration (Screen, etc...)
Many thanks for you help you can bring me,
Bertrand.

So just for the heck of it I did a little research, checked out the wiring diagrams for that car and dug a bit into what I found. Turns out your SWC buttons are digital and transmit to the HU through the LIN bus not CAN bus. The climate controls are on that same bus. Everything on the LIN bus goes to a central module and is sent out to the other modules. The CAN bus also goes to that module but the 2 buses stay separate. Just to make matters more interesting it looks like they use LIN-DC to connect to the HU.
All this means is it's likely the CANbus box they gave you can't even read the commands to the HU and climate control. That would also explain why there are so few manufacturers even selling Volvo specific HU anymore. I checked Ownice and they only mention Bluetooth SWC for that car. Seicane says their HU will retain the car's SWC maybe you can get in touch with them and see if they will sell you their CANbus decoder or at least tell you the part number so you can compare with yours.
Something I overlooked, I don't know how you would do it on your HU but get into the secret menu (usually type a code like 126 while in settings) then type logcan or is it canlog and push the buttons. If there is communication you should see something in the log (you'll have to search the site for info relating to this stuff).
Sounds like a whole can of hurt trying to create a generic system like you suggest at least in your case. Others have already done it you can follow where this link leads to know more.

Hello
First at all, a big thank you for the research done and the explanations (complicated to understand for me )
From what I understood I have to find a way to interface the LIN bus with my Android HU? Right?
From this link, I can read the information of the LIN bus from an Arduino. The question is how can I figure out how to interface my HU with the Arduino? Do you have any information about the link with the HU (CAN BUS or other)?
Link:
(Sorry for format I can't publish link )
The use of a product already manufactured is relatively expensive:
Regarding the secret menu, I have access via a code to the HU configuration menu:
And finally, my idea of a generic system is to decorate the "UC" and "display" to allow for easier physical integration. I could then use any touch screen size and put the "UC" elsewhere in the vehicle. the interconnection between the "UC" and the "display" would be on a more robust connector (HMDI, DisplayPort, etc...)
Another advantage, the screen could be more "fine" than those offered by dealers and better integrate into cars.
That's why I'm looking for a PX3/PX5/PX6 card without a screen.
NB: I found with the file explorer an interesting log file
Thanking you again.
Bertrand.

This is interesting I know the SWC work on BMW and Audi so it probably means that the decoder they gave you can read the LINbus. In the Learning Touch Button screen use the export option to backup the configuration then try the different car types. It might be good to reboot each time and typing this code hctreboot where you type the factory menu secret code might work faster. You can see if there's anything coming through the CANbus by typing canlog instead of the factory menu secret code. It might just be you need to re-learn the keys.

Hello
The problem is that the HU does not detect the connection to the vehicle:
So I'm a little limited on this side to do the analyses.
I'm going 3 weeks on vacation, I couldn't respond too much to this thread during this time, but I'll still try to make the configuration changes in the hidden menu, including the model.
On the other hand, I was wondering if with the LOG transmitted, I could update the Android ROM part?
Thanks in advance,
Bertrand.

Hello
After a well-deserved return from vacation, here I am again!!
With lots of ideas, and especially lots of questions....
1. From the photos, can I put a PX6 in place of the original PX3? (there are Main unit pictures, and CAN BUS picture, if anyone know how to connect to car, for checking error message, etc...)
2. If I put a PX6, how do I install it? via the USB port? knowing I'm on a Chinese make.
3. More complicated: If I realize an interface with an Ardouino for the LIN BUS of my Volvo, could someone help me know how to "inject" the information of the steering wheel controls into the PX3? Is there a standard or something?
Thank you in advance,
Bertrand

Where do you get px6 board?

How did you get inside the “secret” menú?
I soul de like to change mine’s UI after a factory reset....
Thank you!

There are models available from Navitech which handle everything. For the XC60 2011 to 2014 they require that you leave the CPU for the Sensus Display in the car and they interface with that. I assume it is so they can get to the linbus data.
Oddly for 2009-2010 they say that the HVAC info will continue to show on LCD display on top of dash (original monitor). So I'm not sure why your HVAC information is not showing up on the original monitor. Is it possible to leave original CPU for Sensus display in your car?
Check out the Navitech 8.8inch RAM4GROM64G Android 9.0 PX6 on AliExpress.
Items not supported by the Navitech unit: Note:For our head unit, do not support like below: iPod, original car GPS antenna, original car back up rear camera, original car bluetooth, original car USB as well original car Microphone.
I am about to buy one of these for my 2013 XC60

Has anyone on this thread successfully rooted one of these Volvo PX6 MCU devices? Or have the Stock MCU file to restore from incase of a brick.

I have PX6 for Volvo XC60. Here is access to "secret menu": Settings---factory setting---password 1314

General advice for noob, please

I'm totally new to Android head units. Considering one for my 2014 Mazda 3 but, having read through a few threads here, and numerous reviews of different units, I'm concerned that I may be opening myself up to a world of hurt!
So I have a few questions:
1. Is there one unit or brand that is generally recognised as being trouble-free, or minimal bugs?
2. Is there any benefit in buying something from a recognised brand like Alpine for 3x or 4x the price of many of the Chinese units? Are they 3 or 4x better?
3. Long shot - anyone here got a Mazda 3 (BM/BN 2014-2018) and successfully installed an Android headunit, with minimal issues? If so, what make and model
Thanks!

What are your expectations to get with another radio/navigation unit?
Alpine and Kenwood and others are not better, they are different. They all have their built-in issues as any good Android radio... just different ones.
...and yes, buying from a known good supplier is the way you should go. There are some reliable ones, like Klyde, Joying...
You can get universal ones, or some which are specific for your car as plug´n play, like this one:

Understood.
I've been looking at Teyes CC3 (although their UK site doesn't seem to mention available fascia for my car, whereas a random Russian site I found does offer a fascia). But the more research I do, the more I realise I am out of my depth.
I initially wanted something that would run Android Auto, but have quickly come to raise that AA is very limited compared to what these head units can do natively. Having thought about it, this is what I want:
1. Maps, Spotify, WhatsApp, phone calls, DAB radio, all voice controlled. Preferably by Google voice recognition, but I gather that a lot of the Chinese companies intentionally block access to Google voice recog in order to sell their own voice recognition. Whatever, so long as it works.
2. Sleep mode/instant on.
3. AA and Apple CarPlay integration, in case someone else uses my car or I sell it.
4. A solution for the fact my car has Bose amps which require a different level input than most head units put out. Also, a good sound processor. My sound system is pretty good for a stock installed one, and I don't want the head unit to make my music sound trash.
5. Minimum 9" screen, but the bigger the better. Also a fascia solution is required for my specific car, which has the screen sitting on top of the dash.
6. Minimum 4GB RAM, preferably 6 or 8GB, the higher the better.
7. A solution for replacing/adjusting the built in functions from my OEM head unit, such as viewing fuel economy and other settings
8. Integration with my steering wheel controls and commander knob (joystick thingy in my centre console).
I'm sure there are other things that I don't know that I want at the moment, but that's what I've come up with so far, with my limited knowledge.

What you need is a deep integrated unit into the car infrastructure.
That cannot be done with any sort of universal one as produced by Teyes.
...but you need to reduce your expectations a bit...
Voice control is only rudimental available on some devices as "Radio, Navigation, Player..."
Some information from the car are not available. You may can see door open, use the air conditioning and so on. What is working depends on the provided CAN-Box software.
You don´t come around asking the seller, sending some picture of the current dashboard, telling them that you own an OEM sound system and so on.
At least you need a device which is more or less easy to install with all connections preinstalled and someone who is able to answer your questions.
Let me say it like that: Have a look at Klyde units. Ask "Fany" from Klyde by mail: [email protected]
She is a really nice person and competent.
As Klyde is the manufactory themselves, you can personalize your unit.
May be this unit would mostly match to your car: https://www.alibaba.com/product-det...?spm=a2700.shop_plser.41413.28.18803f04itkPz8
Ask her about:
The needed CAN-Box for using with the OEM sound system
The availability of the car menus
The availability of speech input by Google
Chose a PX6 with 8/64 or 8/128GB
Chose an external DAB+ receiver (NO INTERNAL, as they are only usable with the Klyde SW, but you should switch to DAB-z
Add the list of expected functionalities to your mail.
She answers always the next day, mostly within some hours as they are around 6 hrs earlier.
