20How do I navigate with GPS?The Global Positioning System (GPS) is available at any time, free of charge, and is accurate to within 5m (15ft).GPS navigation is made possible by a network of satellites that orbit the Earth at around 20,200km (12,552mi).Each satellite transmits a range of signals which are utilised by GPS receivers, such as your Navman, todetermine an exact location. Although a GPS receiver can detect signals from up to 12 satellites at any time,only four signals are required to provide a position or “GPS fix” (latitude and longitude), for vehicle navigationsystems.How does my Navman receive GPS signals?Your Navman receives GPS signals via the internal GPS antenna. To guarantee the optimum GPS signalstrength, ensure your Navman is outdoors, or in a vehicle outdoors, and has an unobstructed view of the sky.GPS reception is not usually affected by weather, however, very heavy rain or snow may have a negative effecton your reception.How do I view my GPS status?You can view your GPS status at any time from the map screens or the Viewfinder screen. displays greenwhen a GPS fix is established and red when a GPS fix is unavailable. To indicate the reception strength of a GPSfix, displays between one and four green vertical bars. To view your GPS status in more detail, see “GPS Status” on page 80. To set your GPS mode, see “Setting your GPS mode” on page 81.
