SYSTEM DESCRIPTIONPFP:00000
System FunctionsNKS004AB
Here is an example of functions. For details, refer to the owner's manual or navigation system owner's manual.
AUDIO
AudioPilot
® (for BOSE System)
AudioPilot® is the sound improving system that picks up any noises and the sound of music coming into the
vehicle by a microphone under the steering, and that the BOSE amp revises the frequency feature of music at
real time in response to the frequency feature of the noise while driving and listening to music.
If low frequency area noise from vehicle is loud, it adjusts low frequency element of music to be bigger
than vehicle noise.
If high frequency area noise from vehicle is loud, it adjusts all frequency element of music to be bigger
than vehicle noise.
Centerpoint® (for BOSE Surround 5.1ch System)
CD and 2.0ch DVD stereo sound played at audio unit and DVD player are subjected to signal processing in
BOSE amp. It can play the surround sound with presence.
VEHICLE INFORMATION SYSTEM
The status of audio, climate control system, fuel consumption, and navigation system (if equipped) are
displayed.
AV (NAVI) control unit receives the data signal from ECM, unified meter and A/C amp and low tire pres-
sure warning control unit via CAN communication. It calculates the values of fuel economy, tire pressure,
and trip computer from the received information and displays them.
NAVIGATION SYSTEM
Location Detection Principle
The navigation system periodically calculates the vehicle's current
position according to the following three signals:
Travel distance of the vehicle as determined by the vehicle
speed sensor
Turning angle of the vehicle as determined by the gyroscope
(angular velocity sensor)
Direction of vehicle travel as determined by the GPS antenna
(GPS information)
The current position of the vehicle is then identified by comparing the
calculated vehicle position with map data read from the map DVD-
ROM, which is stored in the DVD-ROM drive (map-matching), and
indicated on the screen as a vehicle mark. More accurate data is judged and used by comparing vehicle posi-
tion detection results found by the GPS with the result by map-matching.
The current vehicle position will be calculated by detecting the dis-
tance the vehicle moved from the previous calculation point and its
direction.
Travel distance
Travel distance calculations are based on the vehicle speed
sensor input signal. Therefore, the calculation may become
incorrect as the tires wear down. To prevent this, an automatic
distance correction function has been adopted.
Travel direction
Change in the travel direction of the vehicle is calculated by a
gyroscope (angular velocity sensor) and a GPS antenna (GPS
information). They have both advantages and disadvantages.

More accurate traveling direction is detected because priorities are set for the signals from these two
devices according to the situation.
Map-Matching
Map-matching compares a current location detected by the method
in the “Location Detection Principle” with a road map data from Map
DVD-ROM stored in DVD-ROM drive.
NOTE:
The road map data is based on data stored in the map DVD-ROM.
The vehicle position may not be corrected under the following circumstances and after driving for a certain
time when GPS information is difficult to receive. In this case, the vehicle mark on the display must be cor-
rected manually.
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 vehicle mark has been
repositioned.
If there is an error in distance and/or direction, alternative routes
will be shown in different order of priority, and the incorrect road
can be avoided.
If two roads are running in parallel, they are of the same priority.
Therefore, the vehicle mark may appear on either of them alter-
nately, depending on maneuvering of the steering wheel and
configuration of the road.
Map-matching does not function correctly when a road on which
the vehicle is driving is new and not recorded in the map DVD-
ROM, or when 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-match-
ing function may find another road and position the vehicle mark
on it. Then, when the correct road is detected, the vehicle mark
may change 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 current vehicle position and
the position on the map, correction by map-matching is not possible.
Type Advantage Disadvantage
Gyroscope
(angular velocity sensor)Can detect the vehicle's turning angle quite
accurately.Direction errors may accumulate when vehicle is
driven for long distances without stopping.
GPS antenna
(GPS information)Can detect the vehicle's travel direction
(North/South/East/West).Correct direction cannot be detected when vehi-
cle speed is low.

SATELLITE TUNER
The satellite tuner is connected with the audio unit via communi-
cation line.
It sends the received sound signal from the satellite radio
antenna to the audio unit.
AV CONTROL UNIT (WITHOUT NAVI)
It controls each unit of the system by the operation signal from
the multifunction switch and sends the image signal of operating
condition or vehicle information, etc. to the display unit.
It receives the TEL input voice or the input voice at voice control
from the microphone. It receives the received TEL voice, and
then sends it to the audio unit.
It sends the voice guidance signal to BOSE amp (BOSE sys-
tem).
NAVI CONTROL UNIT (WITH NAVI)
It controls each unit of the system by the operation signal from
the multifunction switch and sends the image signal of operating
condition or vehicle information, etc. to the display unit.
It receives the TEL input voice or the input voice at voice control
from the microphone. It receives the received TEL voice, and
then sends it to the audio unit.
The gyro (angle 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.
Location information is shown on liquid crystal display panel.
FRONT DISPLAY UNIT
It receives the RGB signal and the image signal of video distrib-
utor and camera control unit from AV (NAVI) control unit.
The changing of image is controlled by the communication with

ROUTE CALCULATION AND VISUAL GUIDANCE
The location of vehicle icon is mis-
aligned from the actual position.When using tire chains or replacing the tires, speed
calculations based on the speed sensor may be
incorrect.Drive the vehicle for a while [at approxi-
mately 30km/h (19 MPH) for about 30
minutes] to automatically correct the vehi-
cle icon position.
If this does not correct the vehicle icon
position, contact an INFINITI dealer.
The map data has mistake or is incomplete (the
vehicle icon position is always misaligned in the
same area).Updated road information will be included
in the next version of the map DVD-ROM. Symptom Possible cause Possible solution

sideration, but the same route was calculated. This is not a malfunction.
A waypoint cannot be added.Five waypoints are already set on the route, includ-
ing ones that already passed.A maximum of 5 waypoints can be set on
the route. In case of going to 6 or more
waypoints, perform route calculations mul-
tiple times as necessary.
The suggested route is not dis-
played.Roads near the destination cannot be calculated.Reset the destination to a main or ordinary
road, and recalculate the route.
The starting point and destination are too close. Set a more distant destination.
The starting point and destination are too far away.Divide the way by selecting one or two
intermediate destinations, and perform
route calculations multiple times.
There are time restricted roads (by day of week, by
time) near the current vehicle location or destina-
tion.Set “Use Time Restricted Roads” to off.
A part of the route is not displayed.The suggested route includes narrow streets (roads
displayed in gray).This is not a malfunction.
The part of the route already
passed is deleted.A route is managed by sections between way-
points. If you passed the first waypoint, the section
between the starting point and the waypoint is
deleted. (It may not be deleted depending on the
area.)This is not a malfunction.

Cause (condition) Driving condition Remarks (correction, etc.)
Road
patternY–intersections
At a Y intersection or similar gradual divi-
sion of roads, mistakes in the direction of
travel deduced by the sensor may result in
the vehicle mark appearing on the wrong
road.
If after traveling about 10 km (6
miles) the correct location has
not been restored, perform
location correction, and if nec-
essary, direction correction. Spiral roads
When driving on a large, continuous spiral
road (such as loop bridge), turning angle
error is accumulated and the vehicle mark
may deviate from the correct location.
Straight roads
When driving on a long, straight road and
gentle curve road without stopping, map-
matching does not work effectively enough
and distance errors may accumulate. As a
result, the vehicle mark may deviate from
the correct location when the vehicle
turned at a corner.
Switchback turn
When driving on a zigzag road, the map
may be matched to other roads in the simi-
lar direction nearby at every turn, and the
vehicle mark may deviate from the correct
location.
Roads laid out in a grid pattern
When driving at where roads are laid out in
a grid pattern, where many roads are run-
ning in the similar direction nearby, the
map may be matched to them by mistake
and the vehicle mark may deviate from the
correct location.
Parallel roads
When two roads are running in parallel
(such as highway and sideway), the map
may be matched to the other road by mis-
take and the vehicle mark may deviate
from the correct location.
