GPS Devices can be used for many, many things, not just for navigation, though that is probably the most popular use for it. Today for review I've got a small GPS unit from Qstarz, the BT-1000X Travel Recorder. Don't let the name fool you though, it's much more than a travel recorder. It can be used as a stand alone GPS receiver as well via the Bluetooth connection to you cellphone or computer. The BT-1000X can also be used to geotag your photos and it works with several online services like Google Earth, locr, and flickr to track your way and share your photos and videos with friends. It my time with this product I've found it to be an extremely useful little gadget.
