SPEED DEPENDENT VOLUME CONTROLNJEL0497S13DescriptionNJEL0497S1301If activated, the radio output volume will be automatically adjusted to compensate for increased driving noises
at higher driving speeds.
The radio receives a speed signal from the combination meter and selects the output volume.
PERSONAL AUDIO SETTINGSNJEL0497S14DescriptionNJEL0497S1401The radio is designed to store several settings (volume, bass, treble, preset stations and level of speed
dependent volume control) with every NATS ignition key used. Up to a maximum of 4 NATS keys can be reg-
istered. During the communication mentioned under “Anti-Theft System”,the radio will recognize the used
ignition key and select the accompanying settings.

NOTE:
The road map data is based on data stored in the map DVD-ROM.
SEL686V
In map-matching, alternative routes to reach the destination
will be shown and prioritized, after the road on which the
vehicle is currently driven has been judged and the current-lo-
cation mark has been repositioned.
If there is an error in distance and/or direction, the alternative
routes will be shown in different order of priority, and the wrong
road can be avoided.
If two roads are running in parallel, they are of the same pri-
ority. Therefore, the current-location mark may appear on
either of them alternately, depending on maneuvering of the
steering wheel and configuration of the road.
SKIA0613E
Map-matching does not function correctly when the road on
which the vehicle is driving is new and not recorded in the map
DVD-ROM, or when the road pattern stored in the map data
and the actual road pattern are different due to repair.
When driving on a road not present in the map, the map-
matching function may find another road and position the cur-
rent-location mark on it. Then, when the correct road is
detected, the current-location mark may leap to it.
Effective range for comparing the vehicle position and travel
direction calculated by the distance and direction with the road
data read from the map DVD-ROM is limited. Therefore, when
there is an excessive gap between the current vehicle position
and the position on the map, correction by map-matching is not
possible.

GPS (GLOBAL POSITIONING SYSTEM)NJEL0592S04GPS (Global Positioning System) has been developed and con-
trolled by the US Department of Defense. The system utilizes GPS
satellite (NAVSTAR), sending out radio waves while flying on an
orbit around the earth at the height of approx. 21,000 km (13,000
miles).
The GPS receiver calculates the vehicle’s position in three dimen-
sions (latitude/longitude/altitude) according to the time lag of the
radio waves received from four or more GPS satellites (three-di-
mensional positioning). If radio waves were received only from
three GPS satellites, the GPS receiver calculates the vehicle’s
position in two dimensions (latitude/longitude), utilizing the altitude

data calculated previously by using radio waves from four or more
GPS satellites (two-dimensional positioning).
Accuracy of the GPS will deteriorate under the following conditions.
In two-dimensional positioning, the GPS accuracy will deterio-
rate when the altitude of the vehicle position changes.
There may be an error of approximately 10 m (30 ft.) in posi-
tion detected by three-dimensional positioning, which is more
accurate than two-dimensional positioning. The accuracy can
be even lower depending on the arrangement of the GPS sat-
ellites utilized for the positioning.
Position detection is not possible when the vehicle is in an area
where radio waves from the GPS satellite do not reach, such
as in a tunnel, parking lot in a building, and under an elevated
highway. Radio waves from the GPS satellites may not be
received when some object is located over the GPS antenna.
Position correction by GPS is not available while the vehicle is
stopped.

COMPONENT DESCRIPTIONNJEL0592S05AV and NAVI Control UnitNJEL0592S0501The gyro (angular speed sensor) and the DVD-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 DVD-ROM map.
Locational information is shown on liquid crystal display panel.
PKIA0249E
DVD-ROM DriveNJEL0592S0502Maps, traffic control regulations, and other pertinent information
can be easily read from the DVD-ROM disc.
Map DVD-ROMNJEL0592S0503The map DVD-ROM has maps, traffic control regulations, and
other pertinent information.
To improve DVD-ROM map matching and route determination
functions, the DVD-ROM uses an exclusive Nissan format.
Therefore, the use of a DVD-ROM provided by other manufac-
turers cannot be used.
Gyro (Angular Speed Sensor)NJEL0592S0504The oscillator gyro sensor is used to detect changes in vehicle
steering angle.
The gyro is built into the navigation (AV and NAVI) control unit.

NATS NAVI LINKNJEL0592S22DescriptionNJEL0592S2201The link with the NATS IMMU implies that the AV and NAVI control
unit can basically only be operated if connected to the matching
NATS IMMU to which the AV and NAVI control unit was initially fit-
ted on the production line.
The Navigation system does not operate because it is judged that
the code collation with NATS IMMU is illegal when the control unit
of other cars is installed.
Precautions for AV and NAVI Control Unit
Replacement
NJEL0593When replacing the AV and NAVI control unit, eject the map
DVD-ROM before disconnecting the battery.
The AV and NAVI control unit has the following information
stored in its memory. Record the memory contents before
replacing the control unit, and input them in the new unit as
necessary.

tions
