Maps and GPS
You can use the Global Positioning System
(GPS) to support the Maps application.
Find out your location, or measure
distances and plot coordinates.
Before you can use the GPS function with
your phone, you must pair your phone
with a compatible external GPS receiver
using Bluetooth wireless technology. For
more information, see the user guide for
your GPS device.
After pairing the Bluetooth GPS device
with the phone, it may take several
minutes for the phone to display the
current location. Subsequent connections
should be faster, but if you have not used
GPS for several days, or are very far away
from the last place you used it, it may take
several minutes to detect and display your
location.
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.
