I think alot of the bad radio reception problems result from the antenna being in the back glass. A real upright antenna most likely would work better. Has anyone ever tried it? Just unplug your antenna input from the rear of the stereo, and route a new one to another part of the car - maybe a small upright antenna just to the back and center of the windsheild. Sounds like a lot of work, but a temporary one might give us some answers.
