Description

AV CONTROL UNIT

• The AM/FM receiving function and the CD playing function are equipped.
• Sound signal is transmitted to each speaker.

DISPLAY UNIT

• Display image is controlled by the serial communication from AV control unit.
• RGB image signal (audio operation condition) is input from 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

• Each audio operation can be operated.
• The multifunction switch is connected to the preset switch by wiring harness, 

and it transmits the operation signal to the preset switch.

PRESET SWITCH

• Each audio operation can be operated.
• 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 hard-wire.

STEERING SWITCH

• Each audio operation can be operated.
• Steering switch signal (operation signal) is output to AV control unit.

REAR CONTROL SWITCH

• Each audio operation can be operated.
• The rear control switch is connected via AV communication, and it transmits 

the operation signals of the rear control switch.

ANTENNA AMP.

• Radio signal received by glass antenna is amplified and transmitted to AV con-

trol unit.

• Power (antenna amp. ON signal) is supplied from AV control unit.

CAMERA IMAGE OPERATION PRINCIPLE

• Power is supplied to rear view camera from camera control unit and the rear view camera outputs the cam-

era image to camera control unit when selector lever is set to reverse position and the reverse signal on
camera control unit is input. 

• Camera control unit superimposes the guiding line and predicted course line to the image from rear view

camera and outputs to display unit. In this case, the reverse signal is also input to AV control unit. Therefore,
AV control unit recognizes the selector lever as in the reverse position. And then AV control unit switches the
image displayed by the communication signal between AV control unit and display unit with the camera
image.

• AV control unit outputs camera image signal that is inputted from camera control unit to display unit. 
• Camera control unit controls the direction and distance of predicted course line according to the sensor sig-

nal from steering angle sensor. 

• AV control unit determines whether rear view camera is equipped or not, based on the presence of camera

connection recognition signal. It switches to rear view monitor image at the time of reverse signal input when
rear view camera is equipped.

PREDICTED COURSE LINE OPERATION PRINCIPLE

Detection Of Steering Rotation Direction

Camera control unit detects the rotation direction of steering according to the phase difference of two pairs of
pulse signals (sensor signal 1 and sensor signal 2) input from steering angle sensor. 

Detection Of Steering Neutral Position

The sensor signal 3 input from steering angle sensor is generated at 1 pulse per 1 rotation of the steering
wheel. Camera control unit detects the steering neutral position from this pulse. 

Correction Of Steering Neutral Position

Camera control unit corrects the steering neutral position during driving according to the vehicle speed signal
and sensor signal.
