SYSTEM DESCRIPTION
Revision: 2006 January2006 M35/M45
SYSTEM DESCRIPTIONPFP:00000
System FunctionsNKS00489
Here is an example of functions. For details, refer to the owner's manual or navigation system owner's manual.
AUDIO
Speed Sensitive Volume (for BASE System)
Volume level of this system gone up and down automatically in proportion to the vehicle speed. And the
control level can be selected by the customer.
The audio unit inputs the vehicle signal that is sent from unified meter and A/C amp via CAN communica-
tion through AV (NAVI) control unit.
Precision Phased Audio (for BASE System)
It plays back the sound using the woofer (ultra-low bass and clear midrange sound) and reproduces the
sound with presence.
When the conventional BASS/TREBLE adjustment is a maximum, the sounds might be unclear because
the volume of midrange sound also rises together with the bass and treble. The precision phased audio
can emphasize ultra-low bass and ultra-high treble without changing the midrange sound by digital pro-
cessing using DSP.
NOTE:
When the radio is played, the noise may increase more than the presence due to the characteristics of
broadcasting waves. Therefore, the amplification rate while playing the radio is controlled lower than the
rate while playing CD.
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

AUDIO UNIT
Base System
It receives the TEL voice signal and voice guidance signal from
AV (NAVI) control unit and output them to the front speaker.
When the TEL voice and voice guidance is output, it controls the
volume of each speaker.
BOSE 2ch System
It receives the TEL voice signal from AV (NAVI) control unit and out-
put it to the BOSE amp.
BOSE Surround 5.1ch System
It receives the TEL voice signal from AV (NAVI) control unit and
output it to the BOSE amp.
DVD player receives the received AUX sound and the downmix
sound of DVD player, and then sends them to the BOSE amp.
BOSE AMP
BOSE 2ch System
It amplifies the sound signal from the audio unit and output it to
each speaker.
It receives the voice guidance signal from AV (NAVI) control unit
and output it to the front speaker.
It controls sound volume of each speaker when outputting TEL
voice and voice guidance.
It subjects to AudioPilot® processing when receiving sound sig-
nal from microphone for AudioPilot
® .

BOSE Surround 5.1ch System
It amplifies the sound signal from the audio unit and the DVD
sound signal from DVD player, and then output them to each
speaker.
It receives the voice guidance signal from AV (NAVI) control unit
and output it to the front speaker.
It controls sound volume of each speaker when outputting TEL
voice and voice guidance.
It subjects to AudioPilot® processing when receiving sound sig-
nal from microphone for AudioPilot
® .
It subjects to Centerpoint® processing.
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 front 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 system)
and audio unit (BASE system).
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 front 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 system)
and audio unit (BASE system).
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 DVD player
and camera control unit from AV (NAVI) control unit.
The changing of image is controlled by the communication with
AV (NAVI) control unit.
DVD PLAYER
It sends the sound signal to the BOSE amp and sends the
image signal to the front display unit.
When the downmix function is turned ON when playing DVD,
the sound signal is sent to the audio unit.
It inputs the sound signal from auxiliary input jacks, and then
sends it to audio unit.
CAMERA CONTROL UNIT
When the reverse signal is input, the power is supplied to the
rear view camera, and then the image signal from the rear view
camera is sent to the front display unit.
The camera control unit displays the guiding lines and possible
route lines, and then it synthesizes them to the camera image.
CAN Communication System DescriptionNKS0048B
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.
CAN Communication UnitNKS0048C
Refer to LAN-34, "CAN Communication Unit" .
