Hi everyone,
After a few hours of looking around I found where the connectors for the GPS antenna on the roof of the car is located! From the GPS antenna there are 4 cables - 2 split to the left rear (driver-side) for the XM radio box and 2 split to the right rear (passenger side) - unconnected. See photos in the links below. Just pull off the cover in the rear roof line and go to the left corner. I am checking with Ralf Deventer to find the extension cable to connect from there to the front where the Nav unit will be. Running the cable forward should be straight forward and then you shouldn't need to get a GPS antenna. Hopefully this will save a few bucks and should have the best signal (theoretically).
