Been thru it..... work there and would get in trouble if I took a camera in during working hours. Seems GPSRs are thru out the show. 2nd floor south hall 3 has both Garmin and Magellin. In the central exhibit halls I saw Pioneer and Cobra has their car GPSRs out and proud of them. In the north exhibit halls seems like a lot of the booths have GPS nav systems on display. I don't remember this many GPS systems at last years show.
