hi, i have just purchased my 2001 540i, i just need some info on what to expect to pay and stuff i need to try to get a single din head unit into the dash. i noticed on bavauto that they sell an adpater, but it seems like it would cost a fortune. i just want some info before i bring it to the audio shop. thanks for any help!
