Just got my stereo in the AV replaced yesterday. ?It is a Pioneer 8400 with XM radio. ?JL audio amp and speakers. ?What a difference. ?The XM works great. ?I use it under trees, bridges, and even in the garage. I wonder how they pull off that feat?? 
The XM antenna is mounted on the roof top in the rear by the third brake LIGHT!
Hands down - without a doubt XM Radio is the only way to go.. ?The Onstar still works thanks to OS1 interface. Remember, you need a separate speaker for onstar if you put in an amp!

My mods are almost complete
