Need directions? Looking for a restaurant? Your device has

the tools to get you where you want to be.

You can use applications such as GPS data to determine your

location, or measure distances and coordinates. These

applications require a GPS connection.

The coordinates in the GPS are expressed using the

international WGS-84 coordinate system. The availability of

the coordinates may vary by region.
The Global Positioning System (GPS) is operated by the

government of the United States, which is solely responsible

for its accuracy and maintenance. The accuracy of location

data can be affected by adjustments to GPS satellites made

by the United States government and is subject to change

with the United States Department of Defense civil GPS policy

and the Federal Radionavigation Plan. Accuracy can also be

affected by poor satellite geometry. Availability and quality

of GPS signals may be affected by your location, buildings,

natural obstacles, and weather conditions. The GPS receiver

should only be used outdoors to allow reception of GPS

signals.
Any GPS 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.
The trip meter has limited accuracy, and rounding errors may

occur. Accuracy can also be affected by availability and quality

of GPS signals.
Different positioning methods can be enabled or disabled in

positioning settings.

Your device also supports assisted GPS (A-GPS).
A-GPS is a network service.
Assisted GPS (A-GPS) is used to retrieve assistance data over

a packet data connection, which assists in calculating the

coordinates of your current location when your device is

receiving signals from satellites.
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.
To disable the A-GPS service, select
