: 2005 CTS-V XM Radio location

Anyone know where the XM unit is located? I think I've finally decided to ditch the stock nav unit and go aftermarket. I do like XM/Sirius. So I plan to add a new Sirius unit. I want to use the stock XM antenna, so I need to know the location and type of plug the stock antenna uses.

I'm not positive, but I think it's on the rear deck, passenger side, sandwiched between the metal and cardboard deck cover.
