  1. I’m not sure what the part number is etc. but how would I go about purchasing the MDI kit for my car?

    I see my car has only got the aux-in unlike the American models which came with the MDI kit for the iPod.

  2. Hello.
    Anybody knows if there is an adapter og plug available to connect the rvc to a zenec nc2010 radio ??
    Or just a spare flug to make connections self ???

    best regards Lars

  4. Is it possible to get RCA line out by connecting harness to multipin connector 3 pin 2,3,8
    and at the same time have VW sound amp

    I want to connect a active subwoofer


  5. Patrick, Pins 2,3 and 8 are for the telephone only. If you connected a subwoofer to these, you would only amplify a telephone conversation.

    1. Thanks Tim

      Please tell me how do the connecting with a sub amp to rca510 with original amplifier

  6. Hi all, I bought RCD510 instead of RCD210 but the aerial connectors aren’t the same. Please, do you know if there’s a adapter between them or I have to adapt in manual way?
