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.
 AUX image signal is input from auxiliary jacks.
 Camera image signal is input from camera control unit.
 Composite image (AUX and camera images) signal is output to display unit.
 AUX sound signal is input from the auxiliary jacks.
 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 (AUX and camera images) signal is input from AV control
unit.
 Synchronize signal (HP, VP) is output to AV control unit.
FRONT SPEAKER Outputs sound signal from front speaker.
 Outputs sound (mid and low range).
REAR SPEAKER Outputs sound signal from rear speaker.
 Outputs sound (mid and low range).
FRONT SQUAWKER Outputs sound signal from front squawker.
 Outputs sound (high and mid range).
MULTIFUNCTION SWITCH Operation panel is equipped with the centralized switch where camera, audio
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.
STEERING SWITCH The operations of audio, etc. can be performed.
 Steering switch signal (operation signal) is output to AV control unit.
AUXILIARY INPUT JACKS The image signal of the auxiliary input is output via the AV control unit to the
display unit.
 The sound signal of the auxiliary input is output via the AV control unit to the
each speaker.
