+1 Agreed. Make sure the plug is all the way in and see if the screen lights up. If not, maybe your battery died. Not uncommon for an IPOD battery to kick the bucket.When you plug the iPod in, it should light up and show the BMW logo. Mine has been in the glove box 2 years. Maybe an iPod battery or connector issue. Borrow an iPod from a friend and check it again.
