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.
Assisted GPS (A-GPS) is used to retrieve assistance
data over a packet data connection, which assists in
calculating your current location when your device
is receiving signals from satellites.
A-GPS is a network service.

When the device tries to find satellite signals, the
bar is yellow. When the device receives enough data
from the satellites for GPS to calculate your location,
the bar turns green. The more green bars, the more
reliable the location calculation.
Initially, your device must receive signals from at
least four satellites to calculate your location. After
