So over the last few months I have been getting more and more frequent bouts of FM Radio Interference. When it happens the radio audio will totally cut out and all I here is an RPM dependent whine. It happens on any radio station when I'm not real close to the transmitter. Does not happen when listening to my iPod via the Subaru iPod interface. Car is bone stock with a HK audio system that has never been removed or tinkered with. 54K miles on the car, the plugs and wires have never been replaced.
Did a search and really didn't come up with anything. Any suggestions before I go and change out plugs & wires?
