I have done 3 of these so far, this would be my fourth. Seemed to go fine, reset itself, was playing. Took it out to update my iPod, put it back in and the track 01 was just flashing. I also lost my BMW on Nav screen when I open the door, and the accept screen is gone. IceLink will not play now. I reset the iPod, same thing. When I turn the car off in CD Changer mode, speakers make horrible crackling noise. Any thoughts? I have an '05, not that it should matter.
