Looking at the 530 with or without premium sound but can't find an input jack for an MP3 player. BMW says there is not one installed. Anyone know anything about the Logic7 or standard radios to know if there is a line in port available on the unit? I could always install my own plug if so. My MP3 player has 3000 songs on it with lots of different playlists to match moods. It makes burning CDs obsolete. Can't live without it. [headbang]
