My '05 had the pair of antennas (XM and OnCrap), but my '08 only has one - I asked the dealer, he told me that the remaining roof antenna was for XM, and that the OnCrap antenna was now embedded in the roof (but dealers have never been wrong, right ?)

The cellular, XM and OnStar GPS antenna is all one unit, located just above the driver I believe, on the roof.
There is a 3 coax connection just above the sun visor, the OnStar module is below and behind the radio/climate control head area.
