Installing Sirius in a 2008 Chevy Avalanche

Dec 27, 2008 6:14AM PST

My 2008 Avalanche came with XM radio, but I want to remove it and install a new Sirius radio. When contacting Sirius they recommended to purchase a SIR-GM1, so I did.... Now I am installing the unit but it is not working. The Sirius tech support is now stating that the SIR-GM1 is not compatible with a 2008 Chevy Avalanche.

Has anyone had this problem?
Thanks
