    Just double check you don't own a new M5 first

    (Sorry I had too)

    On a serous note (no pun intended!) I remember having a similar problem in my first car.....check the remote wire and possibly the earth lead

    This is next to always a bad earth. I know this from days of old when fitting huge amplifiers into Corsas and Saxos.

    Chances are you've used the wrong adapter. The speaker input adapter uses a cheap & nasty hi-lo converter which generates alternator whine. Try using the correct RCA input adapter PC9-410 which is just a straight wiring adapter and doesn't use any electronics
