Could you take a measurement, from the top of the rear window to the back of the XM antenna?.....maybe even a pic to show the exactly where you have measured from
OR if anyone has the FSM'* that describe where the antenna should be placed that would also be awseome
Sorry, won't be in the FSM. Already been down that road
Then, when I called GM (corporate) they refused to provide the location and size because adding the antenna is considered a "modification" and they won't support mods (even though it was a factory option)
