    Audi A4 cabriolet B6 non bose aftermarket stereo fit..HELP

    I have removed a symphony 2 head unit and have a pioneer 1600ub to fit. When it didn`t work I have spent several days reading every thread available on loads of sites and still no luck. I have fitted a switched ignition and an aerial booster. The problem I have is when I put the stereo on it...
