N-Series User Manual21How do I navigate withGPS?The Global Positioning System (GPS) is available at any time, free of charge, and is accurate to within5m (15ft). GPS navigation is made possible by a network of satellites that orbit the Earth at around20,200km (12,552mi). Each satellite transmits a range of signals which are utilized by GPS receivers,such as your Navman, to determine an exact location. Although a GPS receiver can detect signalsfrom up to 12 satellites at any time, only four signals are required to provide a position or "GPS fix"(latitude and longitude), for vehicle navigation systems.Your Navman receives GPS signals via the internal GPS antenna. To guarantee the optimum GPSsignal strength, ensure your Navman is outdoors, or in a vehicle outdoors, and has an unobstructedview of the sky. Your Navman can operate in all weather types except snowfall.You can view your GPS status at any time from the map screens or the camera screens. The GPSicon ; displays green when a GPS fix is established and red when a GPS fix is unavailable. Toindicate the reception strength of a GPS fix, ; displays between one and four green quadrants. To see your GPS status in more detail, see "GPS Status" on page 115. For more GPS information, see the GPS Navigation - Frequently Asked Questions guide.
