Well, GlobalSat has done it again. Another new GPS model this year. The BT-328 was a recent release that uses the SIRF GSC2 chipset. The BT-359 uses the SIRF III chipset which has the similar low power capabilities and high sensitivity. Instead of a traditional AC adapter port, the BT-359 uses the mini USB port for recharging. Allowing direct connection to a laptop or an AC adapter module that uses a standard USB connection.
