You must have an internet access point defined in the

device to retrieve assistance data from the Nokia A-GPS

service over a packet data connection. The access point for

A-GPS can be defined in positioning settings. A wireless

LAN (WLAN) access point cannot be used for this service.

Only a packet data internet access point can be used. Your

device asks you to select the internet access point when

GPS is used for the first time.

The GPS receiver is located on the back of the device. When

using the receiver, make sure that you do not cover the

antenna with your hand.
Establishing a GPS connection may take from a

couple of seconds to several minutes.

Establishing a GPS connection 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.

To check how many satellites your device has found, and

whether your device is receiving satellite signals, select

.

If your device has found

satellites, a bar for each satellite

is shown in the satellite info

view. The longer the bar, the

stronger the satellite signal.

When your device has received

enough data from the satellite signal to calculate your

location, the bar colour changes.
To view the positions of found satellites, select 

.

Initially your device must receive signals from at least four

satellites to be able to calculate your location. When the

initial calculation has been made, it may be possible to

continue calculating your location with three satellites.

However, the accuracy is generally better when more

satellites are found.
If no satellite signal can be found, consider the following:
• If you are indoors, go outdoors to receive a better

signal.

• If you are outdoors, move to a more open space.
• Ensure that your hand does not cover the GPS antenna

of your device.

• If the weather conditions are bad, the signal strength

may be affected.

• Some vehicles have tinted (athermic) windows, which

may block the satellite signals.
