Is GM US8 stereo XM capable?
I recently purchased a used 2005 Cobalt LS coupe, with the Pioneer 7 speaker system, and the GM OEM stereo is the US8 option, with MP3 and CD. Everywhere I read, I see that XM is an option on these radios, but the dealer and GM support have no idea how I can get XM in the care... Someone told me that the dealer would have to "program" the radio to accept XM...
Does anyone know how I can get/program a US8 GM OEM stereo for my car, that supports XM?
