Ever needed to occasionally get to a address , don't want to spend a furtune on a fully fledged GPS system , then this is the product for you , by using nav4all , http://www.nav4all.com , a free service that only uses 3G / gprs on your phone , you will be able to navigate to any place on the planet. I have tested this and the 3G / gprs charges at R2.00 / meg work out to only R0.05c per kilometer.
At only one time a GPS unit can ONLY see a maximum of 12 satellites , gps software only needs 3 satellites for position and 4 satellites for position and hight , this unit is a 16 channel unit , more that enough for accurate navigation
GPS Receiver with Bluetooth combines proven wireless technologies that allow you to receive GPS (Global Positioning System) signals and transfer to any Bluetooth enabled mobile devices such as Laptops, PDAs, or Smart Phones with GPS Mapping software installed. The NemeriX power advantage stems from proprietary and patented expertise at the system and block level, as well as customized design of features such as pad rings and carefully controlled layout. Further power savings are derived from intelligent management of on-chip voltage levels, which requires a holistic approach to hardware and software development. Combining NemeriX's deep interdisciplinary know-how with continued investment in specialized low-power design flows, the outcome is chip-level power savings of around 60% compared with competing GPS designs. http://www.nemerix.com/
