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?

Experience Android Unit for VW Touareg 1 (7L) - Year 2008 ?

Hi There,
I have an VW Touareg I from Year 4/2008. It is the Facelift Model with CANBUS 2.0
Buy a Erisin 5056T Unit (PX5 / 2 GB) with integrated VW CANBUS Decoding Box (Decoder inside the Radio it´s not external Box).
Inside the Unit i try different Types of CANBUS settings (Default was 1 (VW / Scoda))
I am little Frustrated because of the limit Implementations of decoding CANBUS Signal inside this Unit.
Whats running:
ACC Signal (Radio turn on when i plug IN the Car Key and go into "Sleep Mode" when i pull the Key out.
Steering Wheel Keys: Only Loud / quiet / Phone / Mute keys are running (can´t change any Responsible of keys in the Unit) seems hard coded
Screen for Camera Switching if i switch my gear into Reverse
Whats not running:
NO , really no Data inside the vehicle App.
Reaktion of draw lines for the backwards Camera change/move only when i turn 100% left or Right on the Steering Wheel. And only for millimeters....
Is there any Experience with other Units that can better Communicate with VW Touareg?
Regards
Ben

no one use a Android Car Unit in the Touareg ?

Hi
Thx for response.
Did you have experience with that Unit?
Can the Radio read the Door or/and Park Sensors?
Regard
Ben

Same here, mine is a px3 android 7.1....... any luck? Have you been able to fix it? My backup diplay works perfectly on ford focus canbus setting....

Hi
Inside the Unit i try different Types of CANBUS settings (Default was 1 (VW / Scoda))#### do you still use this one??

Hello guys,
I have the exact same problem with a Erisin PX5/4gb/Android 9.0, but I have a Treg from 2005 with Canbus 1.6. I have contacted Erisin, sent them my original wiring diagram and am waiting for their response. in the meantime I have the latest MCU updates, I'll try them today.
Have you tried the Canbus setting VW_TOUAREG(Hiworld) ? For me it doesn't work, but maybe for those of you who have Canbus 2.0 will work.
If I find a solution or I have any news I'll post them here, hope you do the same, maybe we will get this unit to decode all the signals from Can-Bus.
If anyone wants the updates images, just let me know and I'll upload them.
Regards,

Steering wheel control problem between Autoradio 8227L and Toyota Yaris II series

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.

Wanqi HU - Steering Wheels Buttons Problem

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.
