Hello all,

I have a 1988 Iroc that I am having a problem with the stock radio. When the radio is turned on all is well, however, within 20 minutes the channels change automatically then the who system fuzzes out. Stations will not tune in until the car is turned off and then restarted. Any suggestions? The car has a power ant that works fine. Thanks PS. Funny thing is I have a 1986 Grand National that does the exact same thing.
