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. GPS
signals may not be available inside buildings or underground and may be impaired
by materials such as concrete and metal.
GPS should not be used for precise location measurement, and you should never
rely solely on location data from the GPS receiver and cellular radio networks 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 coordinates in the GPS are expressed using the international WGS-84 coordinate
system. The availability of the coordinates may vary by region.

Assisted GPS (A-GPS)
Your device also supports assisted GPS (A-GPS).
A-GPS is a network service.
Assisted GPS (A-GPS) is used to retrieve assistance data over a packet data
connection, which assists in calculating the coordinates of your current location
when your device is receiving signals from satellites.
When you activate A-GPS, your device receives useful satellite information from an
assistance data server over the cellular network. With the help of assisted data, your
device can obtain the GPS position faster.
