How does it work?The U.S. goverment maintains a system of 24 satellites orbiting the Earth, called the Global Positioning System (GPS). The GPS satellites transmit positional data. A GPS receiver can receive the satellite signals and determine your location with great precision (typically within about 50 feet). Cobra's mobile navigation products contain a GPS receiver. Also on-board are street maps of the entire 48 US states and major Canadian cities, as well as powerful routing software to calculate a route to your destination. Not only will you always know where you are, you'll also always know how to get to where you want to be!
