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, A/C auto amp. and combination meter via CAN com-

munication 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). 

• The camera image signal is input from the camera control unit. The AV control 

unit outputs camera image signal to the front display unit.

• BOSE amp. ON signal and sound signal are transmitted to BOSE amp.
• Power (signal VCC and inverter VCC) is transmitted to front display.

Without DVD entertainment system

• Auxiliary image and auxiliary sound signals are input from the auxiliary input 

jacks.
With DVD entertainment system

• Composite image signal (auxiliary and DVD images) is input from the video 

distributor.

• Sound signal (DVD and auxiliary sounds) is input from the DVD player.

Description

FRONT DISPLAY UNIT

• Front 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). 

• Synchronizing signal (HP, VP) is output to AV control unit.
• Camera image signal is input from AV control unit.

Without DVD entertainment system

• Auxiliary image signal is input from AV control unit.

With DVD entertainment system

• Composite image signal (auxiliary and DVD images) is input from the AV con-

trol unit.
