I'd like to be able to either listen to my MP3 player or to MP3 CDs while I'm driving, but I have the business radio set-up and 6-Disc trunk player. I don't really want to ruin the feel of my car by swapping out the full stereo and losing the DSP and steering wheel functions, but listening to the same 8 songs gets pretty old. Any advice would help, certainly.
tap into aux hard wire .. back of head unit most stereo shops know how for the newer 7's theres whats called a tuner mod which does almost what im telling you
Get a dice kit or a USA spec kit. They do require you to remove your cd changer but still give you 100% stock use of radio and allows steering wheel control I a dice kit in my car and love it and I just put a USA spec kit in my wife's car and she really enjoys it.
