See attached image...Permanent Radio Glitch w/XM until cold restart. Completely frozen when going into the menu. One thread said something about pulling the Radio fuse, but can't find the fuse box number relating to the Radio in the Manual. 100 Miles RT to the dealer, rather not put the miles on the car if it's an easy fix. Image Unavailable, Please Login As you can see there are few miles on this 488.
