Description

AV CONTROL UNIT

• It is the master unit that controls each operation of the Navigation system.
• The HDD (Hard Disk Drive) is built in, and the map data is stored in HDD.
• The RGB signal (map information) is output to display.
• The voice guidance signal is output to BOSE amp.

DISPLAY UNIT

• Map image signal is input from AV control unit, and it is indicated on display.
• Each operation of navigation can be performed by the touch panel function.

BOSE AMP.

Voice guidance signal is input from AV control unit, and it is output to front LH/RH 
speakers.

FRONT DOOR SPEAKER

Voice guidance signal from BOSE amp. is output.

FRONT SQUAWKER

MULTIFUNCTION SWITCH

• Each operation of navigation can be performed.
• Connected with preset switch via cables and operation signal is transmitted to 

AV control unit via AV communication.

System Description

INFOID:0000000003515973

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 the 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.

• Camera control unit controls the direction and distance of the predicted course line according to the sensor

signal 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
it is equipped.

• Warning message under the rear view monitor display is described by AV control unit.

REAR VIEW MONITOR SYSTEM

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 steering wheel rotation.
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 steering angle sensor signal.
