Travelling The coordinates in the GPS are expressed in degrees and decimal degrees format using the international WGS-84 coordinate system. To set your trip destination, select Options > Set destination and a landmark as the destination, or enter the latitude and longitude coordinates. 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 To clear the destination set for your trip, select Stop navigation. Retrieve position information Select Menu > Applications > GPS > 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. Select Menu > Applications > GPS > 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. 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 Menu > Applications > GPS > 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 orStop. 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 86 © 2009 Nokia. All rights reserved.
