Some Nokia mobile devices have an internal GPS receiver. Those devices do not need an external GPS receiver.
If your device does not have an internal GPS receive, use an external one. Connect the compatible external GPS receiver to your mobile device using Bluetooth technology. When your device finds the receiver, select it from the list displayed. If prompted, enter the pass code of the receiver. Check the user guide of the GPS receiver for the correct code. In most cases, the pass code is 0000.
It may take a few minutes for the GPS receiver to track your position and show it on the map.
You do not need a GPS connection for browsing maps and tracking.
