Description

AV CONTROL UNIT

• Integrates hard disk drive (HDD) allowing map data and music data to be

stored.

• It is the master unit of the MULTI AV system, and is connected to each control

unit by communication. It operates each system according to communication
signals from AV control unit.

• AV control unit includes the audio, hands-free phone, voice control, navigation,

satellite radio, and vehicle information functions.

• It is connected to ECM, unified meter and A/C amp. via CAN communication

to obtain necessary information for the vehicle information function.

• It is connected to BCM via CAN communication transmitting/receiving for the

vehicle settings function.

• It inputs the illumination signals that are required for the display dimming con-

trol.

• It inputs the signals for driving status recognition (vehicle speed, reverse and

parking brake).

• Update of map data is performed with the CONSULT-III and the applicable ca-

ble.

• AV control unit recognizes the presence of camera system with camera con-

nection recognition signal.

DISPLAY UNIT

WOOFER

• Inputs power (amp. ON) and sound signal from BOSE amp.
• Outputs low-frequency sound.

MULTIFUNCTION SWITCH

• Operation panel is equipped with the centralized switch where audio, auxiliary

input and navigation operations are integrated.

• Connected with preset switch via cable, and operation signal is transmitted to

AV control unit via AV communication.

PRESET SWITCH

• Operation panel is equipped with the centralized switch where audio and air

conditioner operations are integrated.

• Connected with multifunction switch via cable, and operation signal is transmit-

ted to AV control unit via AV communication.

• The disk ejection operating signal is performed by hardwire.

CAMERA CONTROL UNIT

• Camera image signal is input from rear view camera. Camera image signal

output to display unit.

• Power (camera ON signal) is transmitted to rear view camera.
• Superimposes the guiding line, predicted course line and sonar indicator to

camera image that outputs to display unit.

• Input the sensor signal from the steering angle sensor, and then control the

predicted course line.

• Camera control unit is connected via AV communication.

REAR VIEW CAMERA

• The image from rear camera is transmitted to camera control unit.
• It receives power (camera ON signal) from camera control unit and operates.

AROUND VIEW MONITOR CONTROL UNIT

• It supplies power to front camera, rear camera, and side camera. And then it

superimposes the images from each camera and outputs them to display unit.

• Superimpose the guiding line, predicted course line and sonar indicator to the

camera image that outputs to display unit.

• It performs the reception/transmission of communication signal with each cam-

era.

• Inputs the sensor signal from steering angle sensor, and then controls the pre-

dicted course line.

• It transmits the sonar operation signal from sonar control unit and receives the

sonar information from sonar control unit via AV communication.

• It transmits the information received/transmitted with sonar control unit via AV

communication to AV control unit.

FRONT CAMERA

• It inputs the power supply from around view monitor control unit and outputs

the image of the vehicle front to around view monitor control unit.

• It performs the reception/transmission of the communication signal with

around view monitor control unit.

REAR CAMERA

• It inputs the power supply from around view monitor control unit and outputs

the image of the vehicle rear to around view monitor control unit.

• It performs the reception/transmission of the communication signal with

around view monitor control unit.

SIDE CAMERA LH

• It inputs the power supply from around view monitor control unit and outputs

the image of the vehicle LH to around view monitor control unit.

• It performs the reception/transmission of the communication signal with

around view monitor control unit.

SIDE CAMERA RH

• It inputs the power supply from around view monitor control unit and outputs

the image of the vehicle RH to around view monitor control unit.

• It performs the reception/transmission of the communication signal with

around view monitor control unit.

INFRARED LED (AUXILIARY LIGHTING)

• It illuminates around the front RH wheel by the power supply from around view

monitor control unit to improve nighttime visibility of Front-Side view.

• The infrared LED is an invisible light ray.
