I searched the board and there is not a lot of topics on the BMW version ipod adaptor. Anyone using? Big difference over Icelink. I see you have to create BMW specific playlists but since I can't do the install myself, and I am not comfortable letting Best Buy do it, I might spring for the BMW version (cost is $149 for the unit and about 1 hr labor). Thoughts? Suggestions? Comments on the BMW unit?
