Hi, I buy android12 HU with MTK8667 for BMW F20. Now in the factory setting select Canbus as Zmyt is can connect with Drive already.
But have problem is when select source from Android screen (touch screen) can't play FM from screen but still use from Drive.
And can't use buttons on the steering wheel for control sound or cheage FM just change mode only.
Problem
- Can't use buttons on streering wheel such as volume +/-, change FM station
- Sound will overlap if playing FM via iDrive and playing music or youtube from android will overlap.
I don't know how the problem is caused by the firmware or the settings, attached the image of the software below, who can help me? If you would like more information, we will be happy to send you information. Because the seller couldn't answer any questions for me.
This unit is not an FYT. Requested moderator move to the generic dumping (Android head-units) forum

Hello!
I´ve recently got a Witson HU (MTCD 1.97a) with the Canbus adapter for my Fiat Bravo (2013).
The steering wheel controls function ok (vol up, vol down,...) but i´ve seen another HU displaying "door opened" or other msgs (displayed in center car display), overwritten on HU display that look like the ones that appear when you change volume...
I tried various canbus settings (i found 2 different for the Fiat Bravo) but neither of them works as aspected. One is ok for the steering wheel controls and the other does nothing. But again... no extra msgs on screen.
Is it ok like this? Maybe the canbus decoder only works for those msgs, and ignore the rest of the canbus data...
any ideas would be appreciated!! thanks in advance!
greetings from Argentina!

That feature doesnt necessarily work on all cars, look for an app like "Car settings" or "Car service" in the apps when you have it set on the 2 Fiat Bravo CAN Bus setting, if you cant find it anywhere, go through all apps, if you still cant find anything, then that feature is not supported. You could also try any other Fiat CAN Bus setting, or maybe Lancias, Alfa or even some Chrysler vehicles theyre all made by FCA so there is a possibility it may work, probably not but worth trying.
You could also try the menu on the car, I know on the Bravo you can control some stuff on the factory nav unit, if you didnt ahve nav in the car it may be a case of turning the feature on via the car before it will work.
After typos1 tip, i set the canbus mode to ALFA ROMEO. The display shows an overhead view of a car, with the doors or boot being opened. Great!!! BUT... i lost steering wheel controls. Bad!!
So i´ll wait for an OS update to fix this thing.
The calibration screen for steering wheel controls doesnt show any option, in any case.
thanks again!

Ah, thats annoying.
The OS has nothing to do with it, its the MCU that deals with this sort of stuff, so an OS update for wont help, an MCU update may do IF they add full support for the Bravo and theres no guarantee that they will.
Some cars have CAN Bus but use resistive SWC (my Alfa is like this, but some Alfas do have CAN Bus SWC) which could explain it.
There may be a way round it if you buy an SWC adapter for your car. These headunits supposedly use the same SWC protocol as Pioneer, so if you got a Pioneer/Fiat Bravo SWC adapter, disconnected the 2 SWC wires from your CAN Bus box and attached them to the SWC adapter it would convert the CAN Bus SWC signal from your car into resistive so the stereo can understand them. AFAIK this has not been done before but it should work.
EDIT : didnt spot the bit about the SWC calibration not showing up, damn, I guess you could extract the SWC app using the app "APKextractor" and see if it installs when the stereo is in Alfa Romeo CAN Bus mode.

browsing other threads i saw there are users with the same issue. SWC app shows just a blank screen (with save and reset buttons on top).
I´m still studying this (among other things... the mtcd HU is nice.. but it looks like it needs polishing)
hi, is your witson still working?
Hi everyone, I hope to be writing in the appropriate section.
I bought an 8227L android car radio:
- http://imageupper.com/s12/1/6/M1568803747176376_8.jpg
- http://imageupper.com/s12/1/6/M1568803747176376_6.jpg
And I have a Toyota Yaris II series:
- http://imageupper.com/s12/1/6/M1568803747176376_7.jpg
This morning I successfully mounted the 8227L stereo in my car
- http://imageupper.com/s12/1/6/M1568803747176376_5.jpg
and everything works fine except the steering wheel controls.
The old original car radio (where steering wheel controls worked) was so connected:
- http://imageupper.com/s12/1/6/M1568803747176376_4.jpg
And when mounting the new autoradio 8227L, I just inserted the cables in the appropriate adapters.
The fact is that as soon as I enter the steering wheel configuration menu, I press START and select a command to associate with a physical steering wheel button, I get an error:
- http://imageupper.com/s12/1/6/M1568803747176376_3.jpg
even trying to reboot:
- http://imageupper.com/s12/1/6/M1568803747176376_2.jpg
- http://imageupper.com/s12/1/6/M1568803747176376_1.jpg
I still get the same error.
Can u help me in some way? Thank u all in advance!
As a first step, I would put a voltmeter onto the sense wires while pressing each of steering wheel buttons- to confirm that different voltages are available for the head unit to learn
This wil prove or otherwise that the wiring is in order.
Hi Pxdev,
First of all thank you very much for your attention.
At the moment I do not have the possibility to use a voltmeter, however I am sure that the steering wheel controls work (tested up to a few hours before the installation of the new radio) and also the installation of the new radio has simply consisted in disconnecting the 3 connectors ( http://imageupper.com/s12/1/6/M1568803747176376_4.jpg the blue and the two whites) visible in the picture and insert them in the appropriate adapters of the new car radio and insert a single connector in the special housing and everything worked, except, of course, for the steering wheel controls. Is there anything else I could try to do? Many thanks in advance.
Hi,
Have you bought it with the Canbus and cables for your car? I have the exact same unit and the steering wheel works well.
I get the same error , found a video saying ground one wire to radio ground and any one key wire ground radio but doesn't work. If anybody has any solution or troubleshoot guide please let me know .
Checked voltage , voltage from headunit around 3.5v , checked resisitance from each key shows different value for each key. Now what to do?
Did you find a solution to your problem as I'm having the same problem with mine. Same head unit with a Raise can bus installed. The steering wheel controls worked fine when I first bought the car but I decided to delete some of the unused apps and since then the steering wheel controls don't work. I can't even remember the name of the app I deleted. Any help would be grateful.
Hey guys,
I recently bought a Headunit for my Opel/Vauxhall/GM Vectra C by the brand Autotop on AliExpress.
More information here : https://www.aliexpress.com/item/33064243426.html?spm=a2g0s.9042311.0.0.4d374c4djb2lMm
It is a RK3368 unit with 4gb RAM and 64gb ROM and Carplay function. I mainly bought this unit because I expected two main features from it.
Firstly I wanted to be able to have plug and play Android Auto and the unit came with a dedicated usb cable that had the label carplay on it which only fit in one slot on the back of the radio. Sadly when I plugged my phone in nothing happened so I assume that the unit is in fact not Android Auto ready even though the description says so. Am I doing something wrong/ Do I have to set up Android Auto in some way, first?
I also want to install a backup camera and I saw in some other youtube videos that the PX5 Android 9 and Android 10 devices have something called "Extra Settings" where different parameters of the backup camera can be adjusted. One of the things that can be adjusted is the calculation of the reverse trajectory of the car which is a feature that I would really like to have.
Unfortunately my headunit only has "General Settings" "Factory Settings" and "Steering Wheel" settings. And none of these settings contain any adjustments for the backup camera.
Is there a way to "unlock" these extra settings or are they just not present in my Android Build ?
Ive attached my Build Number for further information down below
Thanks in advance for your help!

i found out that a cable was not connected to the steering wheel.
I had to open the plastic-frame above the steering wheel and there was a connector.
Now they work but i still can not programm each button to another function. Still grey screen.

I can to program each button in Factory settings --- key --- canbus key setting, they work for me
Can you change the language of the car? After installing the language changed to english from the tachometre. In the car app there is no setting to change language.
I dont mean the android language,
Hi, so recently bought an andoird justnavi head unit from aliexpress ( https://www.aliexpress.com/item/1005002055611288.html?spm=a2g0o.order_list.0.0.21ef18022l8yMV). It works fine as a display for apple carplay and music etc but i still cannot get the reverse camera on my car and the steering wheel buttons to work with it even though i bought a canbus decoder from justnavi themselves. The volume up and down buttons work on the steering wheel but no other button does. I have tried to update the MCU several times but after it restarts the software is still the same version which is frustrating. Does anyone have a fix to this or had a similar problem before. Please let me know. Thanks .

Hello everyone, it's been a while in this forum .
I recently purchased a unit from Junsun with processor UIS 8581A (this was not provided in the add) and started to play with the unit on my SEAT Ibiza 2011 (09-2013)
I noticed that the steering wheel commands are connected through the CANBUS decoder unit from Simplesoft and I am unable to change the keys.
Furthermore I am stuck in a carousel of commands for "MODE" key on the steering wheel tat swaps through NAVI>MUSIC>VIDEO>AUXIN>BT>Ipod and i think something else ) and I only need NAVI and MUSIC.
Details regarding unit:
Platform information TS18
CPU UIS8581A (8CORTEX a55 @1.6GHZ), 4Gb Ram
GPU dual core Mali G-52 3EE
Sound processor AK7604
Radio module TDA7708
Bluetooth 5.0
CAN VERSION:V3.88.139BYPS
MCU VERSION:TS18.1.1
SYSTEM VERSION;TS18.2.2 (20220629)
ANDROID VERSION 11.0
I would like to ask for help for these Issues, questions:
1. Is there any way to change the "Mode" function on the steering wheel control (canbus decoder connected) to only carousel for specific apps.
2. Can I change the default music app to let's say Youtube music?
3. How to change control keys on steering wheel with CANBUS decoder connected? And if it's not possible is there a way without the CANBUS decoder connected, what are the downsides if this can occur?
4. I saw that there is a very big thread on another forum about these units but not here :-? why? (I live in europe and my unit came from Poland)
I searched the forum and tried SWC car switcher app, and some others but the buttons from steering wheel had the highest priority either way :-(
Thank you and sorry for the TLDR!

Some people disabled the standard SWC mode key by removing all apps from factory settings and use it for AppSwitcher:
Post in thread 'AppSwitcher - smart SWC launcher (for Junsun and similar devices) incl. autostart' https://forum.xda-developers.com/t/...-devices-incl-autostart.4435555/post-87531251
Another approach is to check if the SWC of Seat Ibiza is a resistance matrix and the connections are exposed to the wiring harness.

Hi Torsten and thank you for the reply, I tried to remove the apps but unfortunately my factory settings doesn't have that option on TS 18 platform tried with 8878 like in the link you posted :-(. Thank you anyway
