Evening all.
I have an xtrons 4.4 HU, it's fitted with a canbus decoder in and Audi A4.
The HU came with the steering wheel controls preset, I've tried to map them to add my own touch but I can't. When I go into the steering wheel control option, I operate a key and he screen does not recognise this, I've also tried highlighting a button then trying to use a steeeing wheel button and it still doesn't recognise it.
What ami missing guys? All the YouTube and Google tutorials say to do it how I am!
Thanks.
I have the same issue on a 2012 Mazda 3, the head unit only recognizes a direct voltage input from the steering wheel buttons, yours is probably controlled by the CANBUS, with the head unit, there should be 2 wires (Key1 and Key2), they should be connected to the car wiring I believe. Please wait for someone with more experience to confirm.

From what I've read they are connected through canbus but I have no idea how to work around this. Thanks.
Anyone? Tried downloading the rk1188 headunit app but it does nothing!
interested about!
Anyone please?

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!

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 there
I installed a JY-VM131N2 in my 2014 VW Passat. The Steering Wheel is working (out of the stock).
I'd like to change the mapping of the buttons, but all of them shows Parameter 255. Video is attached under the link:
https://1drv.ms/v/s!AiWHrfhlX2gwwytL4cOZcTs_fcov
Can you help me to change the mapping?
Answer from Joying:
Nice day
I am sorry can not support to remap the steering wheel control buttons
Hope you can understand
Can anybody help?

You have a CAN decoder (a little box attached to the harness) that is programmed with a certain steering wheels keys mapping and you can't change that.
Your best chance is to wire the steering wheels buttons directly and bypass the CAN decoder, but it works ONLY IF the steering wheel buttons are the resistive type.
If you don't have the experience please don't try to mess with the wires... things can go wrong with the headunit or the car.
Hi,
I have old cars without steering wheel stereo controls. But maybe some cheap new cars still don't have these, so some may relate.
Universal 2din Head units with px6 4gb and 7" screen (there would be space for more ) don't have skip track/next track button.
I also tried to find if there is way to use some Bluetooth remote with these units, but all info seems to be that it does not work.
I don't want to hard wire controls to steering wheel.
Is there some head unit that I missed? Is there a way to make bluetooth remotes work?
Maybe something with sc9853i has next track button?
BTW i found this video https://www.youtube.com/watch?v=wptzk5W6uxI - i did not know there were any px5 with matte screen!
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_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.
Hello,
I bought an Android unit on July and after some troubleshooting everything was working fine. Now I have a problem. I have a Renault Clio 4 Pre-Restyling and steering wheel controls are managed by CAN-BUS. The problem is that Volume controls and radio station change don't work if I don't turn on Head Lights. Other canbus functionalities seem to be working fine. For example when I open doors I can see them on my video. Could it be the CanBus decoder faulty or I have to check some wire connection? Thank you
Anyone can help me? Do you need any further information? Is it possible to know the pinout of CANBUS connector? Usually is 20 pin.
