I am getting the 05 G6 GT 4 door. it has every option including onstar, and 6 disk monsoon system, but it does not have the factory XM installed. my question is can i buy the receiver and antenna and have it work through the factory installed head unit?
I found the Terk XMDGM100 but it does not list the G6 as a compatable car. It says it needs to be a Class II radio. What class is the monsoon radio on the G6?
