I have XM Radio in my 2007 Avalanche, I have some channels that skip but I don't know or understand why. Say for example I have 70's, 80's, 90's channels set up. That be 7, 8, 9, when go from channel 7 to 8 I can but when I try to go to 9 I can't. I have to manual set it to go to channel 9 in the seek button. When I call XM radio they had to send a refresh signal to it. Still didn't fix the problem. I don't have this problem with basic radio stations but with XM radio. Even when I'm just looking at other stations it skips from station 90 to like 130. But all the channels in between if I manual go to them I can access them. So I don't get what going on. I was thinking maybe a hard reset may work, but I didn't find an option in the settings/menu area of the radio. Any thoughts on how to fix this problem maybe?
