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.
NAV2704
VOICE GUIDANCERoute 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-
CATIONThis 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.CURRENT VEHICLE LOCATION

ACCURACY OF POSITIONINGThe color of the GPS indicator in the lower right
corner of the screen indicates the accuracy of
positioning as follows:. Green: positioning is possible
. Gray: positioning is not possible
INFO:
For approximately 3 or 4 minutes after starting
the system, the GPS indicator remains gray,
even if accurate positioning is possible.
Positioning adjustmentWhen 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 satellitesThe reception of GPS signals can be weak,
depending on the environment. Vehicles in the
following areas/environments may not receive
GPS signals (indicator color: gray) .

General system information

SymptomPossible cause Possible solution
The location of the vehicle icon is
misaligned from the actual position. When using tire chains or replacing the tires, speed calculatio
ns based on
the speed sensor may be incorrect. Drive the vehicle for a while (at approximately 19
MPH for about 30 minutes) to automatically correct
the vehicle icon position.
If this does not correct the vehicle icon position,
contact a NISSAN dealer.
The map data has a mistake or is incomplete (the vehicle icon position is
always misaligned in the same area) . Updated road information will be included in the next
version of the map DVD-ROM.
