GLOBALSAT GPS RECEIVER BT-821
The GlobalSat BT-821 is a high performance, Bluetooth GPS receiver that is WAAS/EGNOS enabled by default and incorporates the 32-channel MTK GPS chipset.
Combining the BT-821's Bluetooth wireless technology with a Bluetooth enabled devices such as Smartphones, PDAs or laptops which support Serial Port Protocol SPP (regardless of their operating system) and your favorite navigation software (street, topo, ocean, aviation), you can create a sophisticated navigation system at a fraction of the cost of larger dedicated navigation units.
The BT-821 offers up to 23 hours of continuous use from a single charge, making it the ideal GPS for extended navigation trips, whether on the road or on the trail. Battery usage is substantially increased by having a built-in auto shut-off feature that powers off the BT-821 after 10-minutes of no active connectivity with the host device. Should the BT-821 ever be accidentally left on when exiting a vehicle, or within a backpack, the auto shut-off feature will power-off the GPS receiver to conserve battery resources.
The BT-821 comes complete with a 12VDC cigarette lighter adapter for in-vehicle charging. The a sleek, compact design of the BT-821 makes it easy to carry in a pocket, purse, backpack or even on a belt when using the optional carrying case
