    top pic looks like main power, battery backup power and possibly light switch (dims the stereo when you put car lights on)

    I think the speakers are on a different block.

  4. Cheers. I need to know exactly which cable is positive/negative etc. I think audi have them slightly differently to other manufacturers

    Fat brown is earth
    Fat red with white stripe is perm live
    Yellow with red stripe is ignition on live
    Bluish one is dimmer
    Green stripe is GALA
    White one next to it is K bus
     
  7. Awesome!! Cheers Andy. You're a legend!
    Found out what GALA is so don't need that. What is K Bus and do I have to connect the brown wire attached to the aeriel anywhere? Thanks

    K bus is a digital data link that can be used to control all sorts of electronics in the car. All it's used for on the OEM HU is to allow it to be turned on for an hour with the keys out.
    The brown wire on the aerial just connects to the chassis of the HU
