i've seen a lot of cars with the antenna for sirius satelite mounted inside the car, like in the back deck of the car and even some on the front dash of the car. mine...on the other hand is stuck right on top the damn car and i hate it there. i wanna move in the car but don't know about the reception???? is it just the same, worse, i doubt it's better but it could be. if anyone has it in the car and thinks it works pretty damn good there, SPEAK UP!!!!!!
