NOTE:
The name MULTIFUNCTION SWITCH indicates the integration of PRESET SWITCH and MULTIFUNCTION
SWITCH virtually.
System DescriptionINFOID:0000000003765828
Multi AV system means that the following systems are integrated.
AV control unit controls by transmitting/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
communication lines (H, L).
Two AV communication lines (H, L) adopt a twisted pair line that is resistant to noise.

MULTI AV SYSTEM
AV 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. Transmitting/
receiving of data signal is performed by BCM. Also, it transmits the required signal of vehicle setting and
receives the response signal.
AV control unit is connected with display unit and serial communication, and it transmits the required signal
of display and display control and receives the response signal from display unit.
NOTE:
AV control unit can perform CONSULT-III self-operating function and on board self-diagnosis.
CONSULT-III self diagnosis: Refer to AV-434, "
CONSULT-III Function (MULTI AV)".
On board self diagnosis: Refer to AV-419, "
Diagnosis Description".
HANDS-FREE PHONE SYSTEM
Hands-free communication can be operated by connecting using Bluetooth™ communication with cellular
phone.
Operation is performed by display unit (touch panel), multifunction switch or steering switch, and operating
condition is indicated on display unit.
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 via TEL antenna 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. The cellular phone outputs the voice signal to
TEL antenna by establishing Bluetooth
™ communication. The signal from TEL antenna is sent to front speaker
via NAVI control unit, AV control unit, and BOSE amp.
DVD ENTERTAINMENT SYSTEM
DVD player is connected with AV control unit via AV communication, and controlled by AV control unit.
DVD image signal is output from DVD player to display unit via AV control unit.
DVD stereo (2ch) sound signal is output from DVD player to each speaker via AV control unit and BOSE
amp.
DVD surround (5.1ch) sound signal is output from DVD player to each speaker via BOSE amp.
