XM Antenna Location

Question for the forum

Where is the XM antenna located for vehicles purchased with this option?
I realize the black shark fin OnStar antenna is located on the trunk, but is this also the XM Antenna or no? If it isn't, where the heck is it?

Yes, its also the XM antenna.

Thanks for the info. My reason for asking is that I am having a new head unit put into my Redline - Pioneer AVIC D2. I am a Sirius subscriber and have purchased the Pioneer SIR-PNR2 module. How do the Onstar and XM antenna lines run up to the head unit. Are there two separate cables - 1 for the XM and 1 for the OnStar?

Could I tell the installers to use the XM Antenna even though it will be for the Sirius? I also need to have the GPS antenna mounted on the trunk area too so that's another one which needs to go on.
