This Bluetooth GPS plugs into the SD card slot of a PDA, and takes power from the PDA device - no need to keep a battery charged in this Bluetooth GPS! You can still use a MiniSD card in this device, so you won't lose the functionality of your PDAs SD card slot.

The HI-505SD is equipped with a 20 channel SirfIII GPS receiver, sensitive enough to work well in the most difficult of areas such as timber forests, and canyons. The HI-505SD can swivel and tilt for optimal reception, depending on how you hold, or mount your PDA (landscape or portrait).
