2003 NISSAN MAXIMA Navigation Manual

WHA T IS A NA VIGA TION
SYSTEM?
ABOUT THE NAVIGATION SYS-
TEM
This navigation system combines the data ob-
tained from the vehicle (by gyro sensor) and
from GPS (Global Positioning System) satel-
lites to calculate the current location of the ve-
hicle. This position is then displayed on the
screen, allowing route guidance to a destina-
tion.
WHA T IS GPS (GLOBAL PO-
SITIONING SYSTEM)?
GPS is a system developed and operated by the
U.S. government, covering the entire globe.
This navigation system receives three or more
different radio signals from NAVST AR (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 US, controls signals
transmitted from GPS satellites. This control
sometimes results in reduced accuracy or no
signal received at all.
ACCURACY OF POSITIONING
The color of the GPS Indicatoron the up-
per left corner of the screen indicates position-
ing as follows:

Green: When positioning is possible and
accurate

Y ellow: When positioning is possible but
not accurate

Gray: When 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 po-
sition information is not accurate based on ve-
hicle speed and gyro sensor data calculations,
the system will adjust the vehicle position in-
formation using GPS signals.
RECEIVING SIGNALS FROM
GPS SATELLITES
Sometimes, satellite reception is weak. The fol-
lowing are places where signals tend to be
weak:

Inside tunnels and parking lots in buildings

Areas with numerous tall buildings

Under multi-layered highways

In a dense forestVehicles in these areas may not receive GPS
signals (Indicator color: gray).
INFO:
The antenna for GPS is located in the instru-
ment panel inside the vehicle.Do not place
any object, especially mobile phones or
transceivers, on the instrument panel.
Because the strength of the GPS signals is 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 INFORMA-
TION
This system displays GPS information.
Please refer to “GPS information display” on
page 11-12.NOTE:
The navigation system does not take
driving in carpool lanes into consider-
ation for the guidance.

DET AILED MAP CO VERAGE
AREAS (MCA) FOR THE
NA VIGA TION SYSTEM
This system is primarily 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 . Information concerning road condi-
tions, traffic signs and the availability of ser-
vices may not always be up-to-date. The sys-
tem is not a substitute for safe, proper , and le-
gal driving.
Map data includes major metropolitan areas in
the United States.
Map data consists of map CD-ROM MCA1 to
MCA9. For information about map CD-ROMs,
contact a NISSAN dealer .
Map data includes 2 types of areas: “Detailed
coverage areas” providing all detailed road
data and other areas showing main roads only .The route calculation may not be made on the
border of the map coverage area and the other
areas.
When driving from one map coverage area
(MCA) into another: No map information is
displayed on the screen when the vehicle is
driven past the mapping border into the new
area. Only the vehicle position icon is dis-
played on the screen. The screen will become
gray indicating that you are outside the MCA
covered by the mapping CD. Replace the cur-
rent map CDwith the new map CDthat con-
tains the information for the new area in which
you are driving. Map information will then be
displayed on the screen for the new area.
NOTE:
Waypoints and destinations cannot be
set for positions outside of a map cov-
erage area. Once the new Map CD is in-
stalled, you will need to reprogram the
waypoints and final destination.
