Volkswagen CAN Interface and Climate Control - MTCB Android Head Units Q&A

Hi All,
I have a JY unit in a 2012 Volkswagen Amarok. The CAN interface is working well SWC and power, illuminate etc are all ok BUT the climate control status is not working.
When the unit first starts, the climate control status continually changes between LO and the actual set point (both passenger and driver set points). Once the set point is changed, it seems to stop. I have the same problem on the Joyous ROM and Malaysk.
Any thoughts?

first I would check "factory settings" for the correct MCU protocol version (please note what was set before changing anything).
If that does not help you could think about an MCU update as a second step

[Question] Board Computer settings are missing

Hi,
has anyone experience with retaining GID/CID controls with RK3188 replaced original car stereo? More specifically I'm interested in Opel
Zafira GID. Currently GID controls can be accessed only from SETTINGS button on radio panel. BC menu can be accessed additionally from steering wheel buttons, but not Settings menu. If head unit has no implementation for accessing board computer settings menu, as it is done with Dynavin for example, then settings control will be lost.
Has anyone bump on this problem with RK3188 specific car head units?
did you configure factory settings and enable CAN-BUS?

Malaysk rom: how to startup app into background and cannot change steering buttons

Hi,
Ik use Malaysk rom (version RK3188) on an seicaneunit in my Mini Cooper R56.
I have some issue's/problems which i cannot solve or get an aswer to...
1.
I want to run the app 'flitsmeister' (a app for traffic info and speed traps warnings). This apps runs in background and popups when it detects traffic or a speed trap, this works OK. But when i start it on boot it stays on top until i press home etc. I would like to start this app on boot and it should run in the background or the home button should be 'pressed' automaticly after a few seconds.
Is there a way to do this in this rom?!
2.
I cannot change the steering buttons control, when i open the menu and press the key to assign it simply performs the default assigned function, i cannot change this in anyway. How can i change the behavour of the steering wheel controls and save this?
3.
Is there a update for a newer android version (5 or 6) for this unit which i can use?
Steerling wheel functionality works through a canbus which most newer cars have. Seicane eonon etc all use canbus.. however thats if your vehicle have one which it should. Problem one.. your missing a canbus..
If you have a canbus 2 issues possible.
Canbus is picky and eah make speaks their own language.. now most chinese aftermarket HU use a multi purpose canbus decoder which your vehicle may not pick up or you have a faulty canbus.
2. Canbus wiring.. now alot of makes run wiring through the oem harness.. depending the hu in the modle of car.. like running a stock crappy system vs an alpine, inifinte, bode system where multipul components talk.. but that then becomes a sound issues differet topic.
The canbus wiring itself could be wrong off the new HU harness you'll have to check seicanes crappy wiring diagram matching to your oem harness. Where the canbus connection is use a multimeter with the car off.., on accessory and started.
Future reference..
Seicane eonon etc have messed up the wiring giving the canbud power even when the car is off.. meaning they ran the power off the battery live wire.. vs just the accessory and on power wire.. draining the battery of your vehicle. Simple fix youll have to just switch the power wire to the correct wire being accessories and on.
At the end of the day you most likely need the canbus for the steering wheel functions to work. Ifcyou have it do soke trouble shooting

Android 7.1.2 PX3, MTCE_MX_V2.74_1 - Peugeot 407 2005-2008

Hi Guys,
Can anyone recommend a CAN bus decoder for this head unit as the one supplied with the radio is great receiving messages from the car, but the head unit / CAN bus decoder combi has very, very limited functionality controlling the car settings (only Auto headlights ON/OFF works).
At the moment the car is stuck in KPH (K/100l) and °F - would really like to get the car back to °C and MPH (MPG). I don't know the CAN bus decoder manufacturer as there is no obvious external markings -
CAN BUS DECODER
MH (PA-SS-07) 20171013
SS-PA073271010-1
For: PEUGEOT 407
P/N: 1814600028
Software: PSA V1.00.012BYPS
Thank for any help
Mobi
I have the same one and it works good. In Car settings I switched it to C and KM
I wish I had a MPG option to chose from and the temperature unit is stuck as °C but displays °F on the display (car settings)

mam ten sam problem na px5 xtce mx2 v2.27_2
I used to have a separate CAR SETTINGS apk to set the i-cockpit info language of my Peugeot.
Can anyone send me a backup of the car setting apk?
I have lost it when I update the mtcd firmware so now I can't set my peugeot car language and it's in French.
I want to change the language back to English. Many thanks.
canbus apk is only visible when the canbus profile matches your car make n model.
Id try changing the profiles back and forth and see if this fixes it.

I have tried to use Canbus 61 PSI Simple for my peugeot 3008 steering wheel control is working.
The control settings apk showed up but not much I can change in there and also there is no language option in there so I can't change the language to English.
I also tried Canbus 50 for Peugeot 3008 rise but nothing is work so look like not much I can do to change the language unless use the old original radio control but it is too much hassle to take this android unit out and reconnect the original radio. Thanks anyway.
Same problem, have you solved it?

Disabled Canbus app to avoid issue? Potential problems?

Hi
I've purchased a PX5 MTCD based Dasaita 10.2" unit for my Peugeot 208 2016 to get Android auto.
Quite pleased with the design and features overall but had a show stopper when I realised that even if I set the unit to mph in the control settings app the car would flip back over to kph on my speedometer when it started up. This was even though the setting stayed as mph in the control settings app. Indeed I'd have to flip back to khp then back again to mph to rectify.
I tried first of all upgrading to the latest version of my DCU software (2.99MTCE) and updated and tried different ROM's to no avail.
Anyway. I've found a sort of workaround I think which is to disable the canbus app in Android settings. This has stopped the speedo from updating and the steering wheel controls still work. Have I broken anything else though? Does anyone know what force stopping this app does?
Thanks
Dasaita provided me with the fix today. If you PM me, I will send you the file and instructions. Note that you do the update at your own risk.
Fix= new firmware? Android or MCU?
Fix is an update for the canbus. It's not an android firmware nor MCU update.
Hi @jamesbruton, how/where do I turn off the Canbus app?

Problem with the can bus Citroen C4 assembly of a dedicated Chinese Headunit.

Hi
I have a problem with the can bus
ciytroen c4 assembly of a dedicated chinese.
The problem appears after plugging the radio into the cube after the serial one, namely the canbus module beeps pulsating. I will add that the radio turns on, receiving stations, they can be operated.
I will add that after configuring the module in the radio settings, the steering wheel buttons work this way. means there is communication and it still squeaks. I tried to insert the bundle with the module also squeaks.
watch it

Hi
If you didn't manage to solve the problem yet...
You need to setup the can bus decoder in your head unit and then the beeping will stop.
If you need help just ask!
Cheers

Hi,
I'm dealing with the same problems.
Some of the car functions you can change over the car settings app.
And there should be a car info app which shows fuel consumption.
I'm still using the OEM multiscreen with steering wheel to change car settings.
But when using that I have the issue that all OEM displays get off and on during driving.
I'm trying to find a solution.

I bought a PSA-RZ-01 decoder. This one doesn't work with my android HU. Maybe I'll try the Hiworld decoder. Really annoying
Are these MTCB type head units?
Did anybody find a fix for this problem.
I have the same problem with the citroen c4 doing a selftest while driving.
And it keeps resetting the small display

True, but I think the problem is related to the canbus module. So wanted to check if someone with similar problems did find a fix
Hi to all. I finally got a newer Andeoid version for my headunit and now all informations I need or I expected are showing on my headunit.
Everything before the update wasn't shown now appears like doors open informations, ECU fault codes, fuel informations and consumption, AC informations everything is shown like a popup information. And all that withe the Rais canbus decoder. The small original display I kept cause of the missing informations on the headunit is now not needed any more.
If someone still have problems with the canbus all you need is to update your andeoid unit to the actual version for your unit.
Can you advise what your canbuse settings are ?
Inside of the factory menu ?
I just installed a android T10 unit with a Raise canbus module. But only thing that is working on my Citroen C4 are the volume buttons...and even that does not work correct. I i press the menu button on my steering wheel sound also go up

Have you gone to Car Settings under factory and selected the relevant file under Can Setting? R011 is for Citroen C4 where the steering keys work fine, however my instrument panel keeps flicking between kmph and mph..
R016 works fine but only volume buttons work and the display screen thinks CD or radio is on.. (see picture)

In my android radio version, I didn’t see anything like “R0..” When I choose version of canbus “raise” -> psa/Citroen -> I have only models of car and I get C4L. Everything works like steering wheel buttons but I have problems with resetting displays and appearing diagnosis.
