17. GPS applications
The Global Positioning System (GPS) is operated by the government of the United States, which is solely responsible for its
accuracy and maintenance. The accuracy of location data can be affected by adjustments to GPS satellites made by the United
States government and is subject to change with the United States Department of Defense civil GPS policy and the Federal
Radionavigation Plan. Accuracy can also be affected by poor satellite geometry. Availability and quality of GPS signals may be
affected by your location, buildings, natural obstacles, and weather conditions. The GPS receiver should only be used outdoors
to allow reception of GPS signals.
GPS should only be used as a navigation aid. It should not be used for precise location measurement and you should never rely
solely on location data from the GPS receiver for positioning or navigation.
The trip meter has limited accuracy, and rounding errors may occur. Accuracy can also be affected by availability and quality of
GPS signals.
The GPS applications in your device require an additional Bluetooth GPS enhancement to operate.
Positioning
Select Menu > Tools > Position..
To select a positioning method, scroll to the positioning method, and select Options > Enable. To stop using it, select Options >

Navigator is a GPS application that enables you to view your current location, find your way to a desired location, and track
distance. The coordinates to locations are expressed in degrees and decimal degrees using the WGS-84 coordinate system.
The application requires a Bluetooth GPS accessory to operate. You must also have Bluetooth GPS positioning method enabled
in Menu > Tools > Position..
The application must receive positioning info from at least three satellites to use it as a traveling aid.
