    I’ve read that the R8 RVC module (420 910 441) can accept an RGB video feed and pass that to the RNS-E when not in reverse, can anybody confirm this?

    Also could somebody please point in the direction of schematics/pinout of the module so I can test the theory?

    I would have thought it the other way around, it has an RGB output and a composite input.

    25 - Screen earth to navigation system with CD drive control unit -J401-
    27 - Video output sync. to navigation system with CD drive control unit -J401-
    28 - Video earth to navigation system with CD drive control unit -J401-
    29 - Video output (blue) to navigation system with CD drive control unit -J401-
    30 - Video earth to navigation system with CD drive control unit -J401-
    31 - Video output, vacant to navigation system with CD drive control unit -J401-
    32 - Video earth to navigation system with CD drive control unit -J401-
    33 - Video output (red) to navigation system with CD drive control unit -J401-
    34 - Video earth to navigation system with CD drive control unit -J401-
    39 - CAN Bus Low (convenience)
    40 - CAN Bus High (convenience)
    43 - Terminal 30
    44 - Terminal 31
    47 - Terminal 31 to reversing camera -R189-
    48 - Voltage supply for reversing camera -R189-

    Should have said, this is not for the camera feed, that is indeed composite and working fine.
    I'm trying to hook up some other kit.

    What I'd read is that the TV module connects to the RVC when fitted with the implication being that the implication being that it can take an RGB feed.

    No, you can't have TV and camera together AFAIK, I've never seen any wiring diagrams for A3/A4/A6/R8/TT with RNS-E/camera/TV

    Since the RVC module has a 54 pin connector and only about a dozen are used I wondered if it might have been true.

    Oh well, worth a try.

    Thanks for the info.

    I agree it is quite wasteful of the 54 pin connector, but the TV tuner uses a 54 pin connector and only uses about 20 of them. The Telephone ECU has a 54 pin and only uses 20 odd of them max if you have a cradle plate.

    It can be done, I’ve got it working with my RNS-E (193 version) and the R8 RVC module :yes:


    RVC pins are:

    11 Video in ‘Blue’
    13 Video in Sync
    15 Video in ‘Red’
    17 Video in ‘Green’

    18 Video in ground/shield

    Usual rules apply, RNS-E goes to message screen when moving over a few miles an hour.
    Reverse camera is automatically selected when you reverse and restores to the video feed after about 5 seconds afterwards.

    Excellent news, not something that is shown on any Audi documentation. Just need to get VIM working on the 193 RNS-E and it's a great solution.
