So, what exactly makes a GPS device good in this crowded market? Important features include a large readable display, a variety routing options, built-in maps, a large points of interest (POI) database, and most importantly, a strong receiver. The SiRF Star III GPS receiver has become the defacto standard for GPS devices because of its fast Time to First Fix (TTFF)- the time it takes the receiver to find its position in a new location- as well as its ability to acquire and maintain a signal even in dense urban environments. (Power consumption is said to be under 15 mW, in 1Hz (map updates every second) tracking mode and acquisition sensitivity is rated at -158 dBm in assisted GPS (A-GPS) and autonomous hot-start modes, and -160 dBm when tracking.) Pricing, an important consideration for most people. LGSF2000 seems to have the both advantages. LGSF2000 is a GPS receiver that is made in Taiwan, where most of the GPS devices are from.

For your battery to reach optimum performance, it is recommended to recharge the battery for 10-12 hours for the first time.
