My XM radio cuts in and out with out good reason to. I found out about the diagnostics mode and got a picture of the XM radio. It seems bad... Any suggestions? The car got hit in driver rear a while ago and I wonder if there might be loose connections or cut wires?? I am waiting till this weekend to pull the truck liner out to get a look at the Sat radio unit. Based on all of the red I am surprised it works at all. Thanks in advance.
