I used to have an iTrip but we just got an X5 so we don't use it anymore because it has a USB function thing. But when we went on holiday to the US we bought a two sided headphone jack. So you put one end in the iPhone and the other car. Or we use this thing from Griffin. Works like the iTrip except it charges it and it is almost like a dock. Check it out at the Griffin website.
My iTrip Auto does not work with my iPhone but some people are reporting success with it. Which one do you have?
thanks
jeff
