I have a weird problem, A few weeks ago I was driving with my family to dinner when my sirius radio displayed "UPDATING CHANNELS".. This process lasted about 30 minutes and afterwords, I had some missing channels that I was able to get before. I called sirius and they were no help at all. I was told by the Sirius rep to take the car to the dealership to have it reset. This past weekend, I disconnected the (-) terminal from my battery and now my up/down express windows don't work anymore.. Has anyone seen a problem like this? If so, what did you do to fix it??
