Another new Bluetooth gadget today: a Bluetooth GPS receiver from PalmTop. The TomTom Navigator Bluetooth GPS is designed for use with Pocket PCs, but will also work with laptops and a few Bluetooth-enabled cellphones like Sony Ericsson’s P800 and Nokia’s 7650 and 3650. These Bluetooth GPS receivers are great because you don’t have to actually connect them to your PDA, and instead just carry it around in a bag or leave it somewhere in your car.
