Thx TomG. I'm still pondering this as I don't own any MP3 players. So for the Ipod setup its going to run me $500. As for the 2005+ Biz CD, I'll probably never find one for a good deal if any! I don't know if my 02 CD/radio even has an AUX port but from what I'm reading around the forum that it doesn't. Are there other MP3 players that are compatible with the X5 and can be integrated as clean as the IPod set up? I definately still like to have the steering wheel controls and ID3 text. The search continues ....
