The YouTube suggestion of rolling up and holding didn't help. What DID help was the dreaded Hard Reset. The only way I could achieve this was to (while key was still on//otherwise roll down). I disconnected NEG for about 10 minutes and then reconnected with key in the off position. The following day, everything works, including the BOSE, which kept doing its own thing, reset time one hour back, and tune Satellite radio to its channel. *** I suspect that towing a UHaul trailer may have contributed to the gremlins.
