I have a 3 week old TDI Jetta with an ipod interface. It worked fine for several weeks then i got a message stating "audio files not found". I thought it was the interface but after hooking up my son's ipod it worked fine. It just for some reason isn't recognizing mine. The ipod works fine when used on its own, it downloads from itunes and does everything else normally. AND it played fine in the car for a while before it stopped. I presume It has to be a problem with the ipod. do any of you young computer savy guys have any ideas?
