I just had XM for a while which came with my H2 and it ran out and I had the GM Sirius Tuner installed at Besy Buy because let's face itthe service is much better. However, when I change channels on the OEM Headunit it cycles through old XM default channels like, "CALL XM", "RADIO ID", and "EMERAGEN". This makes changing channels very annoying. What is wrong?
