GPS data is designed to provide route guidance information
to a selected destination, position information about your
current location, and traveling information, such as the
approximate distance to the destination and the
approximate duration of travel.
The coordinates in the GPS are expressed in degrees and
decimal degrees format using the international WGS-84
coordinate system.
To use GPS data, the GPS receiver of your device must initially
receive position information from at least four satellites to
calculate the coordinates of your location. When the initial
calculation has been made, it may be possible to continue
calculating the coordinates of your location with three
satellites. However, the accuracy is generally better when
more satellites are found.
Route guidance
Select > Applications > GPS data and Navigation.
Start the route guidance outdoors. If started indoors, the GPS
receiver may not receive the necessary information from the
satellites.
Route guidance uses a rotating compass on the device
display. A red ball shows the direction to the destination, and
the approximate distance to it is shown inside the compass
ring.
Route guidance is designed to show the straightest route and
the shortest distance to the destination, measured in a
straight line. Any obstacles on the route, such as buildings
and natural obstacles, are ignored. Differences in altitude are
not taken into account when calculating the distance. Route
guidance is active only when you move.

Select > Applications > GPS data and Position.
In the position view, you can view the position information
of your current location. An estimate of the accuracy of the
location is displayed.
To save your current location as a landmark, select Options >
Save position. Landmarks are saved locations with more
information, and they can be used in other compatible
applications and transferred between compatible devices.
Trip meter
Select > Applications > GPS data and Trip distance.
The trip meter has limited accuracy, and rounding errors may
occur. Accuracy can also be affected by availability and quality
of GPS signals.
To turn trip distance calculation on or off, select Options >
Start or Stop. The calculated values remain on the display.
Use this feature outdoors to receive a better GPS signal.
To set the trip distance and time and average and maximum
speeds to zero, and to start a new calculation, select
Options > Reset. To set the trip meter and total time to zero,
select Restart.
