Have any of you ever had a head unit problem. My cd player stopped working. figured that the kids did something to it. I dont listen to cd because i have Ipod and Satilite raido. Anyway... Now my AM / FM has quite. It scanns channes but its like the antenna is not hooked up.

Sirius work fine as does the ipod hook up, bluetooh and nav.

So any suggestion on what this might be and how to fix it.
