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.

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
AV ( N AV I ) c o n t r o l u n i t .
