In case you use a device with integrated GPS receiver, please have a look into the manual of your device on the location of the GPS receiver. When using the GPS receiver, hold it upright in your hand at an angle of approximately 45 degrees, with a clear view of the sky. Make sure that your hand does not cover the GPS receiver. The time it takes to establish a GPS connection may vary between a few seconds and several minutes. Establishing a GPS connection in the car may take longer.
We recommend that you make use of Assisted GPS (A-GPS) to speed up the connection time for your GPS. A-GPS uses your mobile internet connection to connect to a Nokia server that tells your device which GPS satellites it will be able to connect to, substantially reducing the time taken to get a GPS fix.
If no satellite signal is found, consider the following:
