A Navman SatNav is a GPS navigation system. It takes information from the global positioning network satellites system to determine your current position. The SatNav displays your current position on maps, giving you details on a street level to help you navigate from one location to another. You can use it to find places of interest such as hotels, gas stations, airports and restaurants. If your Navman Navsat isn't working properly, you can try resetting it.
Press the "Power" button to turn on your Navman NavSat.
Press the "Reset" button. The Navman NavSat will reset itself and restart.
Press the "Main Menu" button to bring up the main menu screen, then tap the "Preferences" softkey to reach the preferences menu to do a factory reset, if pressing the reset button did not solve your problem.
Press the "System" softkey in the preferences menu, then press the "Reset" softkey.
Press the "Factory Reset" softkey. This will reset all settings to their factory defaults.
