Our XM reception is crap, we've had Tesla check and they said it's normal -- in a wide open space it's fine. But in rural driving it's worthless. We have 2 other cars with XM that have no issues, so it's gotta be where the Tesla antenna is. Does anyone know how easy it is to get to, and if I can somehow attached an extension antenna, and put it somewhere else in the car. I have a Ranger coming tomorrow to do some other things so maybe he can help me get to the antenna. Any advice would be appreciated!
