The coordinates in the GPS are expressed in degreesand decimal degrees format using the internationalWGS-84 coordinate system.To use GPS data, the GPS receiver of your device mustinitially receive position information from at least foursatellites to calculate the coordinates of your location.When the initial calculation has been made, it may bepossible to continue calculating the coordinates ofyour location with three satellites. However, theaccuracy is generally better when more satellites arefound.Route guidanceSelect Menu > Applications > GPS > GPS data andNavigation.Start the route guidance outdoors. If started indoors,the GPS receiver may not receive the necessaryinformation from the satellites.Route guidance uses a rotating compass on the devicedisplay. A red ball shows the direction to thedestination, and the approximate distance to it isshown inside the compass ring.Route guidance is designed to show the straightestroute 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 whencalculating the distance. Route guidance is active onlywhen you move.To set your trip destination, select Options > Setdestination and a landmark as the destination, orenter the latitude and longitude coordinates.To clear the destination set for your trip, select Stopnavigation.Retrieve position informationSelect Menu > Applications > GPS > GPS data andPosition.In the position view, you can view the positioninformation of your current location. An estimate of theaccuracy of the location is displayed.To save your current location as a landmark, selectOptions > Save position. Landmarks are savedlocations with more information, and they can be usedin other compatible applications and transferredbetween compatible devices.Trip meterSelect Menu > Applications > GPS > GPS data andTrip distance.The trip meter has limited accuracy, and roundingerrors may occur. Accuracy can also be affected byavailability and quality of GPS signals.To turn trip distance calculation on or off, selectOptions > Start orStop. The calculated values remainon the display.
