INFOTAINMENT SYSTEM 163
Global Positioning
System (GPS)
If equipped, the position of the vehicle
is determined by using satellite
signals, various vehicle signals, and
map data.
At times, other interference such as
the satellite condition, road
configuration, condition of the vehicle,
and/or other circumstances can affect
the navigation system's ability to
determine the accurate position of the
vehicle.
The GPS shows the current position of
the vehicle using signals sent by GPS
satellites. When the vehicle is not
receiving signals from the satellites, a
symbol appears in the status bar.
This system might not be available or
interference can occur if any of the
following are true:
.Signals are obstructed by tall
buildings, trees, large trucks, or a
tunnel.
.Satellites are being repaired or
improved.For more information if the GPS is not
