86 roadster. Original Bose/Delco worked then stopped working one week after purchase ( 2007 ). Two summers later everything worked perfect on a 2+ hour cruise then stopped again when I shut car off and restarted. Antenna seems OK, fuses OK, radio display OK. Relay of some sort? Any ideas? Approx. 65,000 miles, 99% garaged. THANKS
GEEZ, no one has an inkling?
