I Thought I had a Sirius Problem...
 

...because only one channel was working for awhile this evening. Weirdest thing. I had radio and nav function, but Sirius was stuck on one channel even though I could toggle through the presets from the steering wheel. Then, as I toggled through the stuck channel, "1234670123" appeared on the multi function dash display. And then, twenty minutes later, everything returns to normal. ?????:confused:

Never saw satellite radio fixed through the FM Principle before...
