About GPS

The availability and quality of GPS signals may be affected by your location, satellite
positions, buildings, natural obstacles, weather conditions and adjustments to GPS
satellites made by the United States government. GPS signals may not be available inside
buildings or underground.
Do not use GPS for precise location measurement, and never rely solely on the location
information provided by GPS and cellular networks.
The coordinates in the GPS are expressed using the international WGS-84 coordinate
system. The availability of the coordinates may vary by region.

About assisted GPS (A-GPS)

Your device supports A-GPS (network service). When you activate A-GPS, your device
receives useful satellite information from an assistance data server over the cellular
network. With the help of assisted data, your device can obtain the GPS position faster.
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.
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.

Access point. Only a packet data internet access point can be used for this service. Your
device asks for the internet access point when GPS is used for the first time.

Hold your device correctly

When using the GPS receiver, ensure 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.
