I have a 2004 Grand Prix with the Monsoon radio, Onstar and XM. I occasionally will hear ignition noise through the speakers, a wine that gets higher with RPM's. And when the car is shut off, even with the door open, I hear static thru the speakers. Anyone have any idea where the problem lies, and if it is something that can be fixed, or something that could cause serious problems?
Thanks in advance!
