ABOUT THE NAVIGATION SYSTEM
This 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 differ-
ent sets of signals are trigonometrically calcu-
lated 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. Consequently, areas such as
military bases may not accurately appear on the
navigation screen.
ACCURACY OF POSITIONING
The color of the GPS Indicatoron the upper
left corner of the screen indicates positioning as
follows:
cGreen: positioning is possible and accurate
cYellow: positioning is possible but accuracy is
minimal
cGray: 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 ADJUSTMENT
When 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
SATELLITES
Sometimes, satellite reception is weak. The fol-
lowing are places where signals tend to be
weak:
cInside tunnels and parking lots in buildings
cAreas with numerous tall buildings
cUnder multi-layered highways
cIn a dense forest
cNear military bases and certain government
facilities
Vehicles in these areas may not receive GPS
signals (Indicator color: gray) .INFO:
The antenna for GPS is located behind the in-
strument panel inside the vehicle.Do not place
any objects, especially mobile phones or
transceivers, on the instrument panel.Be-
cause the strength of the GPS signals are ap-
proximately one billionth of that of TV waves;
phones and transceivers will decrease the
strength or may totally disrupt the signals.DISPLAY OF GPS INFORMATION
This system displays GPS information.
Please refer to “GPS information display” on
page 11-17.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 in-
formation about map DVD-ROMs, contact a
NISSAN dealer or call the NISSAN Navigation
System help desk at 1-800-661–9995.
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 ma-
jor metropolitan areas.
For information on which metropolitan areas are
in detailed coverage areas, please refer to the
NISSAN Navigation System Software Booklet
(included) . When you purchase an updated map
DVD-ROM, a new software booklet will be
provided.

The main feature of the NISSAN Navigation Sys-
tem is Visual and Audio Route Guidance in se-
lected detailed map coverage areas. Utilizing a
network of GPS (Global Positioning System)
satellites, the NISSAN Navigation System tracks
your location on the map and directs you where
you want to go.
Once you program a destination covered by a
detailed map, The NISSAN Navigation System
will determine a route from your current location
to your destination. The moving map display and
turn-by-turn voice commands help the driver de-
termine upcoming turns.
This feature can be especially helpful in finding
unfamiliar locations or businesses. The system
may be unable to set a destination and/or calcu-
late distance when a destination is outside a de-
tailed map coverage area. Additionally, audio
route guidance may not be available if the desti-
nation is outside a detailed map coverage area.
For more information on how to program a
destination, please refer to section 5.The NISSAN Navigation System offers an exten-
sive Point of Interest (POI) directory in detailed
map coverage areas for your convenience. This
directory includes a wide variety of destinations
ranging from gas stations, ATMs, and restau-
rants to casinos, ski resorts, shopping centers
and businesses. By accessing the Point of Inter-
est directory, you can search for addresses and
phone numbers for a destination, and with a
press of a button, the NISSAN Navigation Sys-
tem will calculate a route to the destination.
The Point of Interest directory offers many uses.
For example, the directory can be sorted by the
various types of restaurants near your current
location. If you need an ATM or gas station, the
NISSAN Navigation System can point you to the
closest one or the closest one of your favorite
brand.
For more information on how to use the Point of
Interest directory, please refer to section 6.Using the Address Book feature, you will have
the ability to store up to 50 locations in detailed
map coverage areas into a personal directory.
This is especially useful for frequently visited
locations, such as your clients, relatives, or
friends. The Address Book feature will provide
you with easy access to frequently visited loca-
tions when setting them as your destination.
For more information on how to use your Ad-
dress Book, please refer to section 7.

Symptom Possible cause Remedy
The location names differ, between Planview and
Birdview™.This is because the displayed information is reduced so
that the screen does not become too crowded. There is
also a chance that names of roads or locations will be dis-
played twice. The name appearing on the screen may be
different because of a processing procedure.This should not be regarded as abnormal.
The vehicle icon is not shown correctly. The vehicle might have moved with the ignition off, for ex-
ample on a ferry boat or car transporter.Drive the vehicle with the GPS on for some distance.
The screen does not switch to night screen even after turn-
ing the headlights on.When the lights were last turned on, the last setting was
the daytime screen.Turn the headlights on again, go to [DISPLAY SETTING]
screen and set it to the night screen.
The map does not scroll even when the vehicle is traveling. The display is not switched to the map screen.
Press the MAP
button.
The vehicle icon does not show up. The display is not switched to the map screen.
Press the MAPbutton.
GPS indicator on the screen remains gray. GPS signals are not received because the vehicle is in-
doors or in the shade of buildings.Move the vehicle outdoors with a clear view of the sky.
GPS signals are not received because some objects are
placed on the instrumental panel.Remove the objects from the instrumental panel.
GPS satellites are in poor locations. Please wait for the satellites to move to better locations.
