Android Radios and GM Steering wheel controls - MTCD Android Head Units Q&A

Hey, I have a 2008 Buick and I have a steering wheel control box connected to my current Kenwood. Does the Android radios hook up to that same steering wheel control box or is it some special way I have to do it? Debating on replacing my Kenwood with a Android radio

Typically, the Android radios include a canbus box that interfaces with the stereo. If there is one specifically for your car you should be good to go. Just double check the listing.

BMW E46 canbus

Hello
I Have MTCD Device (GS). I Have newest MCU 1.93. When I select from factory settings canbus: bmw see in apps application: vehicle but not working, also my steering wheel not working. When I set canbus on none my wheel working (ofc all without next/prev - im using mtcdtools for it). With canbus: BMW cant set buttons.
I Think my canbus decoder working if (in canbus option I have set on: none) steering wheel working? Or device has other way for it?

I have mazda cx5 and aftermarket can bus decoder.
My decoder is able to get the reverse signal (it is coded by the can bus) and to transform the steering wheel buttons onto standard signals that can be read by aftermarket stereos (Alpine, pioneer, Kenwood, etc)
If I connect the headunit without can bus decoder, steering wheel buttons work...
If I connected the can bus decoder I had to remap again all buttons...as the signal.is different.
In your case you have a permanent decoder so the signal is transformed always....but the stereo is not recognizing at all.
Do you have any other can bus decoder option apart from.bmw? Try it
Did you check if your connections are on? (Not loose plugs)

Thanks for answer. I have canbus decoder like a: http://www.roadnavi.com/wp-content/uploads/2014/10/RN_CanBUS_Decoder02.jpg
When I select BMW in factory setting I have vehicle app, with other dont see this app. So I think canbus working. I will check leter maybe I need to remap all wheel buttons as u said.
BMW E39, E46 and earlier do not use Canbus if K-Bus, use it from E60, E90

So I need to remove my canbus decoder from device? Or what? How can I enable functions from vehicle app.
I have exact the same issue. Canbus is set to NO. Only that way my steering wheel buttons do work, once I tried the BMW Union and BMW Electronic canbussettings, I am not able to use the steering wheel buttons. Either the vehicle information app does not provide any car specific information.
Seems like to CANBUS decoder I received with my Xtrons (MTCD_GS) does not decode any vehicle information.
The thing I would like is a virtual/graphic PDC, I have it built in OEM. But when I put the car in reverse it doesn't show any PDC, only a blackscreen since I dont have a reverse camera.
Does anyone know how to get more information trough canbus?
I've got a BMW E46 320Ci 1999 (European).

Check the wire connections if you can bypass the swc controls only directly to the headunit and the input of the can-bus for the rest

OK but when I set canbus on BMW (union) I have vehicle app but no informations in, all in blank. So wheel and informations from canbus no working.

Hi,
For me it works in same way. When any CanBus mode is selected then steering wheel keys do not work. Our BMW are using I-Bus to broadcast messages within vehicle entertainment system.
Here is the scheme:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
So our CanBus decoder is not really CanBus but IBus . It is wired to MFL and used only to obtain steering wheel keys events. This is the reason why "Steering Wheel Keys" mapping tool does not work in case of BMW (E39, E38, E46).
As far as I know in VW dedicated units you can control e.g. climate panel (IHKA) using CanBus decoder.
Are you sure that E46 actually had IBus? i thought its only using the kbus?

K-Bus, I-Bus - there is no difference at all. Protocol structure is the same. Just different peripherals are connected to bus line (see picture above).
E46, E39, E38 - all of them have I-Bus.
So when im using the USB Ibus Interface from Rolf Resler and connect it to the radio it should be able to decode the canbus signal?

Yes ibus, there is topic where user creating app for integration with ibus in e46:
http://forum.e46fanatics.com/showthread.php?t=1004766
That guy is also using Rolf Reslers IBUS adapter! Nice
maybe im trying to get one, since its not too expensive at all, but im worried about the cables:
White: IBUS
Red: +12V
Brown: GND
Green: NTSC
Okay, red and brown to the cigar jack. what i have to do with green and white? since i dont have the original monitor, i think that dont need green at all, but where to connect the white? i cant see any infos where its been located i was told to look for the cable on the cd changer, but i dont have one at all.

Hard to say. Between IBus and your head unit (actually MCU) you have CanBus Decoder. I do not know what functionality it has. Maybe simply forwards all of the IBus messages to head unit, maybe it filters it somehow and convert to "understandable" format for head unit. If I were you, then I would start from investigation of canbus decoder first .
Thanks for the research

any news on this mather?
I have a BMW E46 and a RK-A701 unit with android.
I have 4 wires in the unit (CAN TXD, CAN RXD, WC+ and WC2+). How do i have to connect this to the i-bus line from my bmw?
Thanks!
Once again: the BMW IBus has NOTHING in common with the CAN bus (Bosch). You can not connect any CAN interface (neither built-in in your android device nor external device) to your old BMWs IBus.
The only (reasonalble) way of interfaceing imho is to decode the IBus messages using rolfs device and to output voltage levels (DAC) which you feed into the steering wheel control lines of the android device. These input lines take a voltage signal usually generated by a resistor network in the steering wheel button control unit. You would "simulate" the different resistor values by outputting different voltages at the reception of certain IBus messages.
A tinker project as you can see. Not complicated but some work / programming of the IBus device involved.

So, is there any way to remap the SWC keys using the so-called "canbus" decoder on our vehicles? I don't know why the headunit couldn't just remap the keys to a different input. Tried using the IBUS dongle but the response is just wayyy to slow compared to the "canbus" encoder

Canbus to driver dash radio info

Does anyone know how the head unit communicates to the CANBUS and if there is anyway to ensure that the radio info on the driver's dash gets updated reliably?
I find that for example in the radio app, it will update info properly when i change things directly on the head unit, but if I were to use the steering wheel controls, it does not update properly and skip some updates to the dash.
Any help would be great. Thanks.
In my case, radio came with CAN-bus adapter, which was plugged to a large connector which carries power, speakers etc.
CAN is not very standarized, and the adapters are programmed based on reverse-engineering and it is up to unit manufacturer how accurate was the hacking.
What car do you own?

E90 - Android 8.0 Canbus

Hi,
So i ordered this headunit: Hi-azul Android 8.0 Car Autoradio (4GB RAM / 32 GB ROM, PX5) for my BMW E90
Everything seems to be working fine (steering wheel control, door indicators) except from the climate control visualisation, Reverse beep sound and the "vehicle" app doesn't seem to show all informations.
It seems like a problem with canbus i think, I've looked into the canbus settings and only managed to find "BMW Union", so there is not specific canbus entry for E90.
How do i get these other things to work aswell?

I have a dasaita HA2186-MAX6 that doesn't see a Bluetooth device.

So I have a Rockford Fosgate PMX-BTUR(it's a universal steering wheel remote) but my dasaita doesn't see the remote at all, my Oneplus 7 pro does and it connects and works fine. Any idea of how to remedy this?
The remote doesn't have a pin number, just pair it.
I'm running Hal9k rom not sure if this matters
Mcu is 3.40.1
Maybe I have the wrong bt chipset set in settings? I don't get the chipset and how to find if they work or not.

Question Xtrons Head unit for 2010 Lexus IS250, cant get some Steering Wheel Controls to work!

Hi everyone
I have a facelift 2010 Lexus IS250 F Sport, I've had some large success installing this XTRONS head unit for it and I am largely satisfied with it. I am however having an issue with getting Steering Wheel Controls to work with the head unit.
Lexus | Various | Android 10 | Octa Core | 4GB RAM & 64GB ROM | Integrated 4G Solution | PMA10ISLS
XTRONS PMA10ISLS is a 10.1" large screen car stereo with customized face panel and optimized CANbus Decoding for Lexus. It supports CarAutoPlay, built-in DSP, PIP mode enabled ,Dual Theme, Instant Rear Vision and so on.
xtrons.co.uk
Lexus| Various | ISO Wiring Harness | MOST
This ISO Wiring Harness is compatible with XTRONS custom fit units PSP10ISL,PMA10ISL etc. If your car is Lexus IS250/IS300/IS350 Convertible (2-door)with original navigation or fibre amplfier system,you need this cable to aid for the installation.
xtrons.co.uk
This is the unit I purchased, alongside a special wiring harness so that I could use it with my vehicle as its a facelift Navi.
With the default CANbus setting on my head unit, only Volume control seems to work and the phone call buttons and voice command buttons are mapped to functions like Radio and Hey Google but I cannot programme these on the app. With an alternative CANbus setting I get skip track functionality but I get different AC Controls and lose access to my factory amp settings.
The original wiring harness I got for the headhunt has not been used at all as I was instructed to usr the special harness, and that original harness had a CANBUS decoder. XTRONS claim that I am unable to programme the SWC due to the CANBUS needing to decode it, although I have played around with the settings and selected various different CANBUS settings.
Would anyone be able to advise me on how I can get the SWC working, would it involve plugging the CANbus decoder into the head unit? There is a 12 pin connection spare at the back but I am unsure if that would make the difference or not.
