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 .

It receives the image signal from the video distributor.

The changing of image is controlled by the communication with
video distributor.

It receives the operation signal from remote control, and then
sends it to the video distributor.
VIDEO DISTRIBUTOR

It receives the image signal from the AV (NAVI) control unit,
DVD player, and auxiliary input jack, and then sends it to the
front display and rear display.

It supplies the power to the remote control receiver, and then
receives the operation signal from the remote control receiver.

It sends ON signal to headphone amp.
DVD PLAYER
BOSE 2ch System

It sends the sound signal when playing DVD to the audio unit,
headphone amp, and then it sends the image signal to the video
distributor.

It inputs the sound signal from auxiliary input jacks, and then
sends it to audio unit, headphone amp.
BOSE Surround 5.1ch System

It sends the sound signal when playing DVD to the BOSE amp, headphone amp, and then it sends the
image signal to the video distributor.

CAN Communication System DescriptionNKS004AD
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 UnitNKS004AE
Refer to LAN-50, "CAN System Specification Chart" .
