The built-in GPS in your Nokia E55 device finds your location for the purposes of navigating, route planning, and address search. Navigation applications, such as maps, require a GPS connection.
GPS connection means that your device is connected to the Global Positioning System. GPS is not a network or an Internet service.
GPS data should not be used for precise location measurement, and you should never rely solely on location data from the GPS receiver and cellular radio networks for positioning or navigation.
This device also supports Assisted GPS (A-GPS), which is a network service. A-GPS takes satellite information from cellular network towers. It allows faster location acquisition and works in environments where the regular GPS does not necessarily work, such as indoors.
If your device cannot find the satellite signal, consider the following:
Establishing a GPS connection may take from a couple of seconds to several minutes, and in a vehicle may take longer. The GPS receiver draws its power from the device battery. Using the GPS receiver may drain the battery faster.
