Radio Station and Clock Memory Problem
Hello, I'm new to the forum.
I have a 2015 GMC with navigation
The radio always starts out with 87.9 FM like I just disconnected the battery. When I store a radio station or SAT channel in the memory it also does not save it after the key is cycled. The saved time and date is also lost. From what I can tell it only has one fuse for the radio, is there another memory supply fuse like the old days? Any thoughts? I don't have a service booklet. I really don't what to bring it to a dealer. Anyone have a schematic or hints?
Thanks
Mike
