System Description

INFOID:0000000000947004

Multi AV system means that the following systems are integrated.

• Two AV communication lines (H, L) connect between units that configure MULTI AV system. NAVI control

unit controls by sending/receiving data one by one with each unit (slave unit) that configures them com-
pletely as a master unit.

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

meter. It computes and displays fuel economy information value with the obtained information. Sending/
receiving of data signal is performed by BCM. Also, it sends the required signal of vehicle setting and
receives the response signal.

VEHICLE INFORMATION SYSTEM

• Status of audio, fuel economy, maintenance and navigation is 

displayed.

• NAVI control unit displays the fuel consumption status and trip 

computer status while receiving data signal through CAN com-
munication from ECM, combination meter and BCM.

HANDS-FREE PHONE SYSTEM

Refer to the following “HANDS-FREE PHONE SYSTEM”.

< FUNCTION DIAGNOSIS >

[AUDIO WITH NAVIGATION]

MULTI AV SYSTEM

• NAVI 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.

NOTE:
NAVI control unit can perform CONSULT-III self-operating function and on board self-diagnosis.
• CONSULT-III self diagnosis: Refer to 

AV-65, "CONSULT - III Function (MULTI AV)"

.

• On board self diagnosis: Refer to 

AV-55, "Diagnosis Description"

.

HANDS-FREE PHONE SYSTEM

• Hands-free communication can be operated by connecting using Bluetooth

®

 with cellular phone.

• Operation is performed by steering switch, and operating condition is indicated on display.
• Guide sound that is heard during operation is input from NAVI control unit to audio unit and is output from

front speaker.

When a call is originated

Spoken voice sound output from the microphone (Mic. Signal) is input to NAVI control unit. NAVI control unit
outputs to cellular phone with Bluetooth

®

 communication as a TEL voice signal. Voice sound is then heard at

the other party.

When receiving a call

Voice sound is input to own cellular phone from the other party. TEL voice signal is output to front speaker, and
the signal is input to audio unit via NAVI control unit by establishing Bluetooth

®

 communication from cellular

phone.

Description

NAVI CONTORL UNIT

• Map data can be read from the Map DVD-ROM by installing Map DVD-ROM.
• 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 NAVI control unit.

• The NAVI control unit includes the audio, hands-free phone, navigation, and 

vehicle information functions.

• It is connected to ECM and combination meter via CAN communication to ob-

tain necessary information for the vehicle information 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). 

MAP DVD-ROM

A collection of Map data.

DISPLAY UNIT

• Display image is controlled by the serial communication from NAVI control 

unit.

• RGB image signal is input from NAVI control unit (RGB, RGB area and RGB 

synchronizing). Camera image signal is input from camera control unit.

• Synchronize signal (HP, VP) is output to NAVI control unit.
