The Global Positioning System (GPS) is a satellite-based navigation system made up of a network of 24 satellites placed into orbit by the U.S. Department of Defense. GPS was originally intended for military applications, but in the 1980s, the government made the system available for civilian use. GPS works in any weather conditions, anywhere in the world, 24 hours a day. There are no subscription fees or setup charges to use GPS.
After the destination is entered, the service looks for your current location and downloads turn-by-turn text directions onto your phone within a minute or less--depending on the complexity of the directions and the distance. You must then launch the TeleNav or ViaMoto application on the phone, if it's not already running. Select the address you want to go to (or destination name if you assigned one), and follow the voice cues.
