Gunnar - do you have the stock E Class 94-98 head unit in there still? If you don't have a CD changer, and don't plan on having one, you can run the iPod into the CD hookup. USA Spec and Monster make them (go through the Crutchfield "What fits my car" sequence). I've asked for the USA Spec interface for the holidays - hoping to get it setup in the pass side rear quarterpanel of our wagon (where the CD cable should be....I hope).
