So my new 07 GT came with a six month subscription but I don’t seem to get all the channels it skips around. Was wondering if anyone else had this problem and how they fixed it? Thanks

 

Sounds like the initial synch with the Sirius network didn't complete. I had a similar problem with a portable radio and just called their customer support line. They were able to refresh. This happens if the radio looses connectivity with the satellite during the initialization.
