Your device is preconfigured to use the Nokia A-GPS
service, if no service provider-specific A-GPS settings are
available. The assistance data is retrieved from the Nokia
A-GPS service server only when needed.
To disable the A-GPS service, select

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.
Tips on creating a GPS
connection
If your device cannot find the satellite signal, 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.
Check satellite signal status —  To check how many
satellites your device has found, and whether your device
is receiving satellite signals, select 
Menu
 >
Applications
 > 
GPS data
 and 
Options
 > 
Satellite
status
.
If your device has found
satellites, a bar for each satellite
is displayed in the satellite
information view. The longer
the bar, the stronger the
satellite signal is. When your
device has received enough
data from the satellite signal to
calculate your location, the bar colour changes.
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.
Position requests
You may receive a request from a network service to
receive your position information. Service providers may
offer information about local topics, such as weather or
traffic conditions, based on the location of your device.
When you receive a position request, the service that is
making the request is displayed. Select
