I'm pretty sure it a wiring issue but where I couldnt tell you. Evry time I hit a pot hole or a big bump in the road d2 cuts off. I listen to xm 99.9% of the time, so I havent noticed if it does it to cd,radio, av or is it strickly xm. Anybody have a clue whats going on?

Bad wiring

I tested with the other sources (radio,av,cd) doenst shut off. So it is strickly XM that is shutting off when I hit bumps? Any ideas Im checking all my conections right now.
