    Wow Joako,
    Thats the best description of the MOST bus that I have seen, despite searching forums many a time. It confirms what I thought that it is too complex to interfere with the MOST bus itself.
    However the LVDS connection is a video connection giving direct access to the display and I didn't realize until now it is also a standard connection just like the other video connections on a ITX PC, however the ITX PC must also have an LVDS connector. There are lots that can be found sites, by just searching "ITX LVDS", and use an adapter lead. I am just searching around to see what the options are as the video could be displayed on the screen, and then use a modified IPOD adapter it should be possible to use the PC as a media player to output mp3 sound or video.

    First of all great post with all that MOST information, I'm sure that will help a lot of people in the future. (In fact I may hijack it and put it on BMW-Carputers.com.


    But You missed the one main point of the OP's original question. (See highlighted text)

I can now use the buttons with my IBus adapter to control Roadrunner ( in theory) What I need help with is setting up an independant IBus network in my car, what parts do I need from an E46 to relay messages from my wheel to the Ibus adapter? [HL]I've tried connecting the wheel directly to the IBus adapter and powering it but the IBus software doesent detect any button presses so perhaps I need an E46 BCM to relay the IBus traffic? Or does anybody on here know how I would build a small circuit to do this task for me?[/HL]

    Retrofitting IBus to a car that doesnt have it to control a carputer might be beneficial to a lot of people on here so any help would be great.
    Cheers.....

    He has replaced his steering wheel with an iBus compatible one and is/was looking to get that working.


    Now having successfully retrofitted an iBus compatible MF E46 steering wheel into an E36 I can say that all he needed is a 10K resistor.

    Pin assignments at plug connector X13814
    1 E Signal, microphone Voice control microphone
    2 M Shielding Video module
    3 E Video signal, red Video module
    4 E Video signal, green Video module
    5 E Video signal, blue Video module
    6 E Signal, microphone Voice control microphone

    I think I need to take a closer look at the these, it looks like RGB and audio, inputs into the CCC. There must be a catch as this seems to simple! Also I noticed that the rear camera input connects here into Pin 2 and 4. This sounds reasonable as the RGB connection 4 is sync on green.

    Anyone have pin-out details for the video module, as this must also pump RGB straight in to the CCC.

    Hi, sorry to drag up an old thread, but do you have the pinouts for this plug here (8 pin (4)) ? (and the smaller 4 pin plug of the external button)?
