When I start out driving, I hear a squeaking sound that sounds like it is coming from the dash area. It is very hard to tell where it is coming from and it sounds sort of like styrofoam squeaking. It squeaks only when the car is going over bumps. The squeak goes away completely after a few miles and the remainder of the trip is quiet.

I have read several threads. It is not coming from the front suspension or the rear middle seat belt. I suppose it could be from the passenger seat but it does not sound like it is coming from there and it happens whether or not there is a passenger in it. It doesn't seem to be the sunroof, center speaker, or tweeters.

I have tried pushing on everything close by and nothing will make it go away other than time. It kind of sounds like it is behind the radio.
