ABOUT THE NAVIGATION SYSTEMThis navigation system combines the data ob-
tained 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 on the screen, allow-
ing route guidance to a destination.GPS is a system developed and operated by the
U.S. Government, covering the entire planet.
This navigation system receives three or more
different radio signals from NAVSTAR (GPS
satellites), orbiting the earth 13,049 miles
(21,000 km) above ground. The data from dif-
ferent sets of signals will be trigonometrically
calculated to obtain the position of the vehicle.
INFO:
The tracking center in the U.S. controls signals
transmitted from GPS satellites. This control
sometimes results in reduced accuracy or no
signal received at all in accordance with govern-
ment requirements.
ACCURACY OF POSITIONINGThe color of the GPS Indicator
on the upper
left corner of the screen indicates positioning as
follows:
Green: positioning is possible and accurate
Yellow: positioning is possible but accuracy
is minimal.
Gray: positioning is not possible

INFO:
For approximately 3 or 4 minutes after system
startup, the GPS indicator
remains gray,
even if accurate positioning is possible.
POSITIONING ADJUSTMENTWhen the system judges that the vehicle posi-
tion information is not accurate based on vehicle
speed and gyro sensor data calculations, the
system will adjust the vehicle position informa-
tion using GPS signals.RECEIVING SIGNALS FROM GPS
SATELLITESSometimes, satellite reception is weak. The fol-
lowing are places where signals tend to be
weak:
Inside tunnels and parking garages
Areas with numerous tall buildings
Under multi-layered highways
In a dense forest
Vehicles in these areas may not receive GPS
signals (Indicator color: gray).INFO:
The antenna for GPS is located on the instru-
ment panel inside the vehicle.Do not place any
objects, especially mobile phones or trans-
ceivers, on the instrument panel. Because
the strength of the GPS signal is approximately
one billionth of that of TV waves; phones and
transceivers will decrease the strength or may
totally disrupt the signals.
DISPLAY OF GPS INFORMATIONThis system displays GPS information.
Please refer to “GPS information display” on
page 11-17.
NOTE:
Directional guidance provided by the navi-
gation system does not take carpool lane
driving into consideration, especially when
carpool lanes are separated from other
road lanes.This system is designed to help you reach your
destination, and also performs other functions as
outlined in this manual. However, you, the driver,
must use the system safely and properly. Infor-
mation concerning road conditions, traffic signs
and the availability of services may not always be
up-to-date. The system is not a substitute for
safe, proper, and legal driving.
Map data covers select metropolitan areas in the
United States.
Map data is available on map DVD-ROM. For
information about map DVD-ROMs, contact a
NISSAN dealer or call the NISSAN NAVIGA-
TION SYSTEM HELPDESK at 1-800-
NISSAN-1 (1-800-647-7261) for U.S., and at
1-800-777-0325 for CANADA.
Map data includes 2 types of areas: “Detailed
coverage areas” providing all detailed road data
and other areas showing “Main roads only”.
NOTE:
Detailed map data is not available in many
areas and is generally limited to select
major metropolitan areas.
For information on which metropolitan areas are
in detailed coverage areas, please refer to the
