INFOID:0000000000964520

NOTE:
The name MULTIFUNCTION SWITCH indicates the integration of PRESET SWITCH and MULTIFUNCTION
SWITCH virtually.

System Description

INFOID:0000000000964521

Multi AV system means that the following systems are integrated.

• AV control unit controls by sending/receiving data one by one with each unit (slave unit) that configures them

completely as a master unit by connecting between units that configure MULTI AV system with two AV com-
munication lines (H, L).

• Two AV communication lines (H, L) adopt a twisted pair line that is resistant to noise.
• AV control unit is connected by CAN communication, and it receives data signal from ECM, unified meter

and A/C amp. It computes and displays fuel economy information value with the obtained information. Send-
ing/receiving of data signal is performed by BCM. Also, it sends the required signal of vehicle setting and
receives the response signal.

• AV control unit is connected with display and serial communication, and it sends the required signal of dis-

play and display control and receives the response signal from front display. Also, it is connected with satel-
lite radio by serial communication, and it sends the operating signal and receives the display signal.

VEHICLE INFORMATION SYSTEM

• Indicates the status of audio, climate control system, fuel econ-

omy and maintenance.

• AV control unit displays the fuel consumption status while re-

ceiving data signal through CAN communication from ECM, 
unified meter and A/C amp and BCM.

AV control unit can perform CONSULT-III self-operating function and on board self-diagnosis.
• CONSULT-III self-diagnosis: refer to 

AV-26, "CONSULT - III Function"

.

• On board self-diagnosis: refer to 

AV-19, "Diagnosis Description"

.

SATELLITE RADIO SYSTEM

• Satellite radio tuner is controlled by communication signal and request signal with AV control unit.
• Audio signal (satellite radio) is received by satellite antenna and sent to AV control unit. AV control unit is

output the audio signal (satellite radio) to each speaker.

AUXILIARY INPUT SYSTEM

• Image and sound can be output from an external device by connecting a device with auxiliary input jacks.
• Operation can be performed with multifunction switch and steering switch. Multifunction switch sends opera-

tion signal to AV control unit with communication.

Description

AV CONTORL UNIT

• It is the master unit of the MULTI AV system, and it is connected to each con-

trol unit by means of 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 unified meter and A/C amp via CAN communica-

tion to obtain necessary information for the vehicle information function.

• It inputs the automatic brightness ON/OFF signals that are required for the 

display dimming control.

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

parking brake). 

• Auxiliary image signal is input from the auxiliary input jacks.

DISPLAY UNIT

• Display image is controlled by the serial communication from AV control unit.
• RGB image signal is input from AV control unit (RGB, RGB area and RGB 

synchronizing). 

• Synchronize signal (HP, VP) is output to AV control unit.
• Auxiliary image signal is input from the AV control unit.

FRONT DOOR SPEAKER

• Outputs sound signal from AV control unit.
• Outputs high, mid and low range sounds.

REAR DOOR SPEAKER

• Outputs sound signal from AV control unit.
• Outputs high, mid and low range sounds.

TWEETER

• Outputs sound signal from AV control unit.
• Outputs high range sound.

MULTIFUNCTION SWITCH

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

auxiliary input operations are integrated.

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

AV control unit via AV communication.

• The CD ejection operating signal is performed by hardwire.

STEERING SWITCH

• The operation 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, and it outputs the sound signal to the AV control unit.

ANTENNA AMP.

• Radio signal received by glass antenna is amplified and sent to AV control 

unit.

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

SATELLITE RADIO TUNER

• Inputs the satellite radio signal from satellite radio antenna and outputs the
