    Retrofit MMI 3G for 2013 AUDI A7 with RMC headunit

    Hi!
    I try to retrofit my original car headunit RMC with new MMI 3G. The problem is that, wiring and Pinout of New Headunit is different with original one. After use tranfer socket to connect, Screen can start but cannot Pop Up, MMI control no signal ( i research and found out that there is not connect and signal provide for MMI control --> screen cannot POP UP)

    Any one here can help me to find the wiring diagram, where to provide power and signal for MMI control unit wiring? I very need it to re-connect new socket in MMI 3G host.

    Many thanks!

    The engineering problems are likely insurmountable. It would be like proposing to land a rocket booster section on a barge floating in the middle of the ocean.
