Sounds fair based on the fact that I tried with my 2000 X-5 and it is nearly impossible with the manual to get the radio out then the hole left is not std size and you have to wire EVERYTHING separately (maybe you could use the speakers!) There is an adaptor (www.ssiamerica.com ) for certain BMW models for access Aux in thru the CD changer Email them to see if it works on yours. This is the only known crack in the BMW data bus arrangement. Rumuors are the Phat noise (now Kenwood ) mp3 system will interface at some point but as they say It's not an Empeg. Good luck and post if you run into info on adaptors or finish the install
