NISSAN 2011 Pathfinder - Manual (Page 197)

DETOUR
If you want to make a detour due to traffic
conditions, you can use the Detour function to
calculate an alternative route. The NISSAN
Navigation System can calculate a route using
secondary roads that will return you to primary
roads after a specified number of miles.
For more information on the Detour function,
refer to section 5.
Birdview TM
Two map types, 2-dimensional Plan View and 3-
dimensional Birdview
TM , are available in the
NISSAN Navigation System. Birdview TM dis-
plays the map from an elevated perspective. In
Birdview
TM , it is easy to recognize an image of
the route because it provides a panoramic view
over a long distance.
For more information on Birdview TM , refer to
section 3.
VOICE GUIDANCE
Route guidance is provided through voice and
visual instructions. Voice guidance announces
the appropriate directions when approaching an
intersection at which you need to turn.
For more information on voice guidance, refer to
section 5.
DISPLAY OF CURRENT VEHICLE LO-
CATION
This navigation system combines the data
obtained from the vehicle (by gyro sensor) and
from GPS (Global Positioning System) satellites
to calculate the current location of the vehicle.
This position is then displayed throughout route
guidance to a destination.
WHAT IS GPS (Global Positioning
System)?
GPS is a position detecting system that uses
satellites deployed by the U.S. government. This
navigation system receives radio signals from
three or more different satellites that orbit
13,049 miles (21,000 km) above the earth in
space, and detects the position of the vehicle by
utilizing the principle of triangulation.
Positioning adjustment
When the system judges that the vehicle
position information is not accurate based on
vehicle speed and gyro sensor data calculations,
the system will automatically adjust the position
of the vehicle icon using GPS signals.
Receiving signals from GPS satellites
The reception of GPS signals can be weak,
depending on the environment. Vehicles in the
following areas/environments may not receive
