6. GPS Status
Signals are transmitted by Global Positioning System (GPS) satellites orbiting the Earth.
You can view your GPS status at any time from the 2D Map, 3D Map, Next Turn and Next 4 Turns screens.
The GPS Strength Indicator will display green when there is a valid fix (2D or 3D), and between
one and three bars will display to indicate the strength of the signal; the GPS Strength Indicator will display
red when no fix is available.
Tap the GPS Strength Indicator to open the Satellite Signal Strengths screen.
For more detailed information on your current GPS fix, see GPS Status on page 59.
