Visiontac VGPS-700  is another pretty small and stylish GPS receiver. The first is the Navicore, which just barely beats out the Visiontac in a volume competition.

How does this one compare to the Navicore? The Visiontac comes out to be 23,574 cubic millimeters, and the Navicore is 21,120 cubic millimeters.

Both GPS receivers use the SiRF Star III chipset, and both connect with Bluetooth to whatever devices you have that support GPS inputs. The Visiontac has 17-20 hours of battery life, and comes in a piano glass finish.
