PrecautionsNLEL0510WARNING:
Do not attempt to disassemble the monitor. Parts of the monitor have high voltages that can result in
severe and dangerous electric shock.
CAUTION:
+Do not reverse battery connections.
+Do not attach unauthorized parts.
+Protect the unit from severe impact.
NOTE:
Before beginning repair, determine whether or not the unit is defective. Refer to ªThis Condition Is Not
Abnormalº (EL-432).

System DescriptionNLEL0512OUTLINENLEL0512S01The Navigation System (Multi-AV System) relies upon three sens-
ing devices in order to determine vehicle location at regular time
intervals.
1. Vehicle speed sensor: Determines the distance the vehicle has
traveled.
2. Gyro (Angular velocity sensor): Determines vehicle steering
angle and directional change.
3. GPS antenna (GPS data): Determines vehicle forward move-
ment and direction.
The data provided by the three sensing functions together with a
comparison of the mapping information read from the CD-ROM
drive permit accurate determination of the vehicle's current location
and subsequent course (map matching). The information appears
on a liquid crystal display.
This comparison of GPS data (vehicle position sensing) and map
matching permits precise determination of vehicle location.
SEL684V
Position Sensor Operating PrinciplesNLEL0512S0101The sensor determines current vehicle location by calculating the
previously sensed position, the distance traveled from this position,
and the directional changes occurring during this travel.
1. Distance traveled
The distance traveled is calculated using signals received from
the vehicle speed sensor. The sensor automatically compen-
sates for the slightly reduced wheel and tire diameter resulting
from tire wear.
2. Forward movement (Direction)
Changes in the direction of forward movement are calculated
by the gyro (angular velocity sensor) and the GPS antenna

GPS (Global Positioning System)NLEL0512S0103GPS is the global positioning system developed and operated by
the US Department of Defense. GPS satellites (NAVSTAR) trans-
mit radio waves and orbit around the earth at an altitude of approxi-
mately 21,000 km (13,000 miles).
GPS receiver calculates the three-dimensional position of the
vehicle (latitude, longitude, and altitude from the sea level) by the
time difference of the radio wave arriving from more than four GPS
satellites (three-dimensional positioning).
When the radio wave is received from only three GPS satellites, the
two-dimensional position (latitude and longitude) is calculated,
using the altitude from the sea level data calculated by using four
GPS satellites (two-dimensional positioning).
Positioning capability is degraded in the following cases.
+In two-dimensional positioning, when the vehicle's altitude
from the sea level changes, the precision becomes lower.
+The location detection performance can have an error of about
100 m (300 ft) even in three-dimensional positioning with high
precision. Because the precision is influenced by the location
of GPS satellites used for positioning, the location detection
performance may drop depending on the location of GPS sat-
ellites.
+When the radio wave from GPS satellites cannot be received,
for example, when the vehicle is in a tunnel, in a parking lot
inside building, under an elevated superhighway or near strong
power lines, the location may not be detected. Turbulent/
electric weather conditions may also affect positioning perfor-
mance. If something is placed on the antenna, the radio wave
from GPS satellites may not be received.

COMPONENT DESCRIPTIONNLEL0512S02NAVI Control UnitNLEL0512S0201+The gyro (angular speed sensor) and the CD-ROM drive are
built-in units that control the navigation functions.
+Signals are received from the gyro, the vehicle speed sensor,
and the GPS antenna. Vehicle location is determined by com-
bining this data with the data contained in the CD-ROM map.
Locational information is shown on liquid crystal display panel.

Map CD-ROMNLEL0512S0203+The map CD-ROM has maps, traffic control regulations, and
other pertinent information.
+To improve CD-ROM map matching and route determination
functions, the CD-ROM uses an exclusive Nissan format.
Therefore, the use of a CD-ROM provided by other manufac-
turers cannot be used.
SEL690V
Gyro (Angular Speed Sensor)NLEL0512S0204+The oscillator gyro sensor is used to detect changes in vehicle
steering angle.
+The oscillator gyro periodically senses oscillatory variation at
the oscillation terminals. This variation is caused by changes
in the vehicle angular velocity. Voltage variations are sensed
by ceramic voltage sensors at the left and right sides of the
terminals. Vehicle angular velocity corresponds directly with
these changes in voltage.
+The gyro is built into the navigation (NAVI) control unit.
