RE: 2000 Lincoln TownCar Radio
Chuck, FWIW we've had OEM radios in our fleet of Ford pickups that have gone bad and our parts guy just called the local dealer for the nearest repair facility info and sent it out for repair once they advised him of replacement costs. I donored mine once since I had an aftermarket head unit sitting around. It was weeks before we got the repaired unit back. We kept it and put it back in mine before it was traded. I don't remember the specifics but it wasn't cheap.
