5.1 GPS
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), or red when no fix
is available.
For more detailed information on your current GPS fix, see Section 17.8.

The lower left corner of the display also indicates the Qube modem signal strength.

check the connections.
