Two AV communication lines (H, L) adopt a twisted pair line that is resistant to noise.
AV control unit is connected by CAN communication, and it receives data signal from ECM, combination
meter. It computes and displays fuel economy information value with the obtained information. Transmitting/
receiving of data signal is performed by BCM. Also, it transmits the required signal of vehicle setting and
receives the response signal.
AV control unit is connected with display unit and serial communication, and it transmits the required signal
of display and display control and receives the response signal from display unit.
NOTE:
AV control unit can perform CONSULT-III self-operating function and on board self-diagnosis.
CONSULT-III self diagnosis: Refer to AV- 2 11 , "
CONSULT-III Function (MULTI AV)".
On board self diagnosis: Refer to AV-200, "
Diagnosis Description".
DVD ENTERTAINMENT SYSTEM
DVD player is connected with AV control unit via AV communication, and controlled by AV control unit.
DVD image signal is output from DVD player to display unit via AV control unit.
DVD stereo (2ch) sound signal is output from DVD player to each speaker via AV control unit and BOSE
amp.
DVD surround (5.1ch) sound signal is output from DVD player to each speaker via BOSE amp.
Operation can be performed with multifunction switch, steering switch and rear control switch. Multifunction
switch and rear control switch transmits operation signal to AV control unit by AV communication.
AUXILIARY INPUT SYSTEM
Image and sound can be output from an external device by connecting a device with auxiliary input jacks.
Operation can be performed with multifunction switch, steering switch and rear control switch. Multifunction
switch and rear control switch transmits operation signal to AV control unit by AV communication.

Part name Description
AV CONTROL UNIT It is the master unit of the MULTI AV system, and it is connected to each control
unit by communication. It operates each system according to communication
signals from the AV control unit.
AV control unit includes audio function and vehicle information function.
It is connected to ECM and combination meter via CAN communication to ob-
tain necessary information for the vehicle information function.
It is connected to BCM via CAN communication transmitting/receiving for the
vehicle settings function.
Composite image signal (AUX and DVD images) is input from DVD player.
Camera image signal is input from camera control unit.
Composite image (DVD, AUX and camera images) signal is output to display
unit.
Sound signal (DVD and AUX sounds) is input from the DVD player.
Power (signal VCC and inverter VCC) is transmitted to front display unit.
DISPLAY UNIT Display image is controlled by the serial communication from AV control unit.
It receives the power (signal VCC and inverter VCC) from the AV control unit
and operates.
RGB image signal is input from AV control unit (RGB, RGB area and RGB syn-
chronizing).
Composite image (DVD, AUX and camera images) signal is input from AV con-
trol unit.
Synchronize signal (HP, VP) is output to AV control unit.
BOSE AMP.Inputs sound signal from AV control unit and DVD player, and outputs sound sig-
nal to woofer and each speaker.

Outputs sound (high and mid range).
REAR SQUAWKER Outputs sound signal from BOSE amp.
Outputs sound (high and mid range).
CENTER SPEAKER Outputs sound signal from BOSE amp.
Outputs sound (high and mid range).
MULTIFUNCTION SWITCH Operation panel is equipped with the centralized switch where camera, audio,
DVD and auxiliary input operations are integrated.
The multifunction switch is connected to the preset switch by wiring harness,
and it transmits the operation signal to the preset switch.
PRESET SWITCH Operation panel is equipped with the centralized switch where audio and air
conditioner operations are integrated.
The preset switch is connected via AV communication, and it transmits the op-
eration signals of the preset switch and multifunction switch.
The disk ejection operating signal is performed by wiring harness.
CAMERA CONTROL UNIT Camera image signal is input from rear view camera. Camera image signal
output to AV control unit.
Power supply is transmitted to rear view camera.
AV control unit recognizes the presence of camera system with camera con-
nection recognition signal.
Camera control unit is connected via AV communication.
REAR VIEW CAMERA The image of vehicle rear view is transmitted to camera control unit.
It receives the power supply from the camera control unit and operates.
STEERING ANGLE SENSOR Sensor signal (steering angle) is transmitted to camera control unit.
