Default FS: SIR-GM1

This came out of the H3 since we have a different setup now. Basically, if you have a GM car 2003 or newer, with factory XM, this tuner will go in between your XM antenna and your radio and will play Sirius channels instead of XM. Works great. The XM antenna can be used with this too.

$75 including shipping, obo
