I've got a canbus box, Signal for Transmission in reverse is received by the HU.
but thats the only sign of anything canbus related working.
The Wheelkey Study app is empty:

Any advice?

Is it set to BMW in Canbus menu in Factory Settings menu?
Go into Settings.
scroll down
select "Factory Settings"
enter Password 126

Yep,
there are 2 kinds,
BMW
BMW electrical
I tried both, without result unfortunately.
thanks for your input

In my E38 steering wheel keys work when I set "no canbus" in mentioned settings.

Have you tried flashing latest firmware? I think your unit is KD, just like mine.
Only flash anything if you know what you are doing, I take no responsibility for bricked radio.

Fiat Bravo & Canbus messages

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?

Steering wheel control mapping help.

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?

You may get it working but good luck finding updates. I bought a new android deck.

But do you have any user manual of this model?
Or, can you help with the correct config settings of the canbus (P/N.: DF-RZ-02) or other settings of this stereo unit?
Thanks

No unfortunately not. It was installed in my used VW when I bought it. It runs on Windows Platform that’s all I know.
For 100.00 you can get yourself a new android unit from alibaba. Sorry this is bad advice but that’s why I have up and bought a new one. I looked everywhere and the most I found were some sites in russia selling this unit.

Go to car settings > factory settings > 0000 and it's the second line I guess, it's the one the has CAN on the text. Inside that sub menu, choose Nissan

PX5 Steering Wheel controls

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.

Bmw x5 e70 problem mit android HU

Hello everyone. It is a BMW X5 E70 2008, ccc. I bought HU on Aliexpress (the version is in the picture). After installation, the OEM BMW menu does not work (no signal), the usb does not show and the electronic steering wheel adjustment does not work. All cables well connected, checked several times. Can someone help me enable these functions? Thanks in advance
Hi , did you get CANBUS box with this unit?
Canbus is used to connect multimedia device with car functions and car ECU.
If you have one installed probably wrong settings are set for car. You can change it in factory settings menu (hidden menu with PIN code access).
And consult with your seller about bought head unit rather than writing problems here on forum.
As for system update, you can ask seller for update or find on this forum or net, by search term "ZLH_BMH" - that's your version of software for unit.
Hello and thanks for your reply. I have the canbus and it is connected properly. Checked several times by an auto electrician. Everything works as it should except the oem bmw menu. In the factory settings you're talking about, I tried all the options, but it's always the same - no signal. I think it's definitely a software problem and I can't find an update here or anywhere. And the seller is completely useless

I would try to change canbus box with other one, another model like HIworld or Simplesoft, obviously there is no communication between ecu of car and head unit or cables behind unit for keys / steering wheel are misconnected or misswired. Check for wiring diagram for this device, find it one net somewhere.
