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.
