Got my Sky back from the dealer after getting the faulty connector replaced and now the XM feature on the radio does not work. Even pushing the BAND button will not select XM. During troubleshooting the Tech must have spiked the electronics and caused the radio to fail. I could tell something was wrong when the time on the radio showed about 1 hour off. The gremlins are having fun sneaking around on my car. Now I get to go back to the Dealer, they now know me on a first name basis.
I thought the radio was bad. Per the service invoice the lead tech "called TAC case 10165584 instructed to remove 10AMP UHJB fuse #56 for 5 mins and reinstall". My XM now works This fuse also has something to do with ON-STAR. I would like to see a schematic of all of this.
