Hey Klaus:
I thought the story of the XM Radio install was over for me, but there is a confusing wrinkle after all. The radio has taken to shutting off from time to time. It completely shuts down -- even the lights on the radio controls go off. It then comes back on in about a minute. The clock resets to 12:00 when it does this. I presume this means all power to the radio unit is cut being cut off and then reestablished.
This morning, on a 1 1/2 hour ride, it shut off twice in the first 10 minutes of the trip, reset twice and then operated fine until I parked. When I got done with business, I started the truck and made a call using On Star before turning the radio on and the radio knobs again went out, as did the clock. After about a minute, the whole thing came back on and the person I had been talking to was still on the phone. Once I was finished with the call, I turned on the radio, set the program to XM, reset the clock and drove about 1 1/2 hours without further problems.
It is almost as if a circuit breaker is getting hot, opening and shutting everything down, and then closing again after a little cooling.
Do you have in your collection of service bulletins anything that might explain my mysterious radio condition? It was not doing this before the XM install, so I suspect it has something to do with that.
