There is a thread somewhere related to this.I have the 6 disk changer in now and want to get XM through the deck. I'm told by my dealer that I can't. But I thought as long as you had one of the upgraded radio I could. NEED HELP!!!!!!
I had a question regarding that. For those who do not have the XM "fin" on the back, where is the onstar antenna?My understanding was that the XM antenna is integrated into the OnStar antenna, but ONLY if you order the XM option. Thus, no XM ordered, no XM antenna built in.
Better than hearing it's 2 miles behind you."It is on I-5, two miles north of Alicia Parkway."
Funny - that's exactly where I was!
