Downloading A-GPS data involves data transfer through your service provider’s
network. While roaming, that is, outside your service provider's network, the data
transfer charges may be higher than expected. Therefore, by default, A-GPS is not used
while roaming, but this means that calculating your location may take longer than when
using A-GPS.
To allow using A-GPS while roaming, select

Net-assisted GPS
. For information about data transfer charges, contact your
service provider.
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. GPS signals may not be
available inside buildings or underground and may be impaired by materials such as
concrete and metal.
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.
GPS receiver
If your device has an internal GPS receiver, you can use it with Maps.
Using the internal GPS receiver may drain the device battery faster.
Use an external GPS receiver
1 Fully charge your compatible GPS receiver, and switch it on.
2 Set up a Bluetooth connection between your device and the GPS receiver.
3 Place the GPS receiver in a position with an unobstructed view to the sky.
4 Open the Maps application, and select the external GPS receiver.
It may take several minutes to establish the first GPS connection. Subsequent
connections are faster, but, if you have not used GPS for several days, or you are very
far from the last location you used it, it may take a while to find a strong satellite signal.
You can also use Maps without a GPS receiver to browse maps, search for addresses and
locations, and plan routes.
