Outstanding Bluetooth GPS Receivers
Bluetooth is a communications protocol between wireless devices. When traveling with your Phone-PDA-GPS or laptop you do not have to worry about bringing all those connection cables. After the proper configurations are made Bluetooth need any button pushing. When two or more devices enter a range of up to 30 feet of each other, they will automatically begin to communicate without you having to do anything. Bluetooth uses a technique known as frequency hopping and doesn’t interfere with or got sent into a tizzy by other radio waves. Bluetooth operates with very low power so Bluetooth devices can go for several hours between charges.
The major celluar carriers recommend the GlobalSat BT-359 Bluetooth GPS Receiver for their Smartphones. The Holux GPSlim 236 Bluetooth GPS Receiver is also worth a look.
