SYSTEM

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

CAN COMMUNICATION

AV control unit Input Signal

DESCRIPTION

Multi AV system means that the following systems are integrated.

COMMUNICATION SIGNAL

• AV control unit function 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.
• AV control unit is connected with front display unit and serial communication, and it transmits the required

signal of display and display control and receives the response signal from front display unit.

CAN COMMUNICATION

• AV control unit is connected by CAN communication, and it receives data signal from ECM and combination

meter. It computes and displays fuel economy information value with the obtained information.

• The AV control unit, which has the vehicle setting function, transmits and receives data on vehicle setting

condition via CAN communication with the BCM.

• AV control unit receives steering angle signal from steering angle sensor via CAN communication and per-

forms control of predictive course line in rear view monitor image.

Audio system operation can be performed with multifunction switch, preset switch, or steering switch.
• Operating signal is transmitted to AV control unit with AV communication when it is operated by multifunction

switch or preset switch.

• The disk eject signal is transmitted to AV control unit by hardwire, when disk eject switch is operated.
• Operating signal is transmitted to AV control unit with steering switch signal when it is operated by steering

switch.

• Operation status of audio is indicated at front display by RGB image signal, RGB area signal, and RGB

image synchronizing signal.

AM/FM Radio Function

• AM/FM radio tuner is built into AV control unit.
• AM/FM radio wave is received by radio antenna, next it is amplified by antenna amp., and finally it is input to

AV control unit.

• FM radio wave is received by FM sub antenna, and it is transmitted to the AV control unit directly.
• AV control unit outputs audio signal to each speaker.

Satellite Radio Mode

• Satellite radio tuner is controlled by communication signal and request signal with AV control unit.
• Sound signal (satellite radio) is received by satellite radio antenna and transmitted to AV control unit via sat-

ellite radio tuner.

• AV control unit outputs audio signal (satellite radio) to each speaker.

CD Mode

• CD function is built into AV control unit.
• AV control unit outputs audio signal to each speaker when CD is inserted to AV control unit.
• For further information about CD function specifications, refer to

AV-128, "AV Control Unit"

USB Connection Function

• Connecting iPod

or USB memory allows the driver to play iPod

music files or USB memory-stored music

files.

• Sound signals of music files stored in iPod

or USB memory is transmitted from the USB connector to the

AV control unit.

• AV control unit outputs sound signal to each speaker.
• iPod

is recharged when connected to USB connector.

• Compliant USB memory and data recorded are limited.

• Only files that meet the following conditions will be played.

NOTE:
• iPod

is a trademark of Apple inc., registered in the U.S. and other countries.

• Image signals cannot be received from iPod

or USB memory.

• Use the enclosed USB harness when connecting iPod

to USB connector.

DVD PLAYBACK FUNCTION

• DVD is played by inserting DVD into the AV control unit.
• DVD image signals are transmitted to the front display unit, and DVD sound signals are transmitted to each

speaker.

• DVD image signals and sound signals are transmitted to the rear display unit. The rear display unit transmits

the sound signals to the headphone via infrared communication.

• For further information about DVD function specifications, refer to

SYSTEM

Image and sound (DVD, USB memory-stored video data, and auxiliary input) played by AV control unit can be
enjoyed in rear seat using rear display unit and headphone.

Operating Signal

• The mobile entertainment system can be controlled by one of the remote controller.
• It receives the operation signal of the remote controller by the remote control receiver built into rear display

unit, and then transmits it to the AV control unit.

Headphone Sound

Headphone sound signals are transmitted to infrared communication between rear display unit and head-
phone.

Screen rear display

• Image signal output from AV control unit is transmitted to the rear display unit.
• The rear display unit receives the composite image signal (DVD, USB memory-stored video data, and auxil-

iary input) from the AV control unit.

• The rear display unit switches composite images through the communications with the AV control unit via AV

communication.

BLUETOOTH

HANDS-FREE PHONE FUNCTION

• TEL adapter unit is controlled with AV communication from AV control unit.
• When the cellular phone is connected to the TEL adapter unit via TEL antenna in Bluetooth

communica-

tion, hands-free phone communication can be performed.

• Simply operating the steering switch without releasing hands from the steering wheel allows the driver to

make a phone call or receive a phone call.

• When a Bluetooth

communication compliant phone is registered to the TEL adapter unit, hands-free phone

communication can be performed. Five units of Bluetooth

communication devices can be registered to the

TEL adapter unit.

• The content of the memory (telephone book) of the cellular phone can be recorded in the TEL adapter unit.
• TEL adapter unit has the on board self-diagnosis function. Refer to

AV-159, "On Board Diagnosis Function"

When A Call Is Originated

• Spoken voice sound output from the microphone (microphone signal) is input to TEL adapter unit.
• TEL adapter 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 input to TEL adapter unit by establishing Bluetooth

communication from cellular phone,

and the signal is output to front speaker.

AUXILIARY INPUT FUNCTION

• Image and sound can be output from an external device by connecting a device with front auxiliary input

jacks.

• AUX image signals are transmitted to front and rear display unit via AV control unit
• AUX sound signals are transmitted to each unit as follows:
- To each speaker via AV control unit.
- To the rear display unit via AV control unit, and headphone sound signals are transmitted to infrared commu-

nication between rear display unit and headphone.

REAR VIEW MONITOR FUNCTION

Operation Description

• When the selector lever is shifted to the reverse position, the rear view monitor image is displayed.
• When the selector lever is shifted to any position other than the reverse position, the original image (the

image displayed before the rear view monitor image) is displayed.

Camera Image Operation Principle

• The AV control unit that receives the reverse signal input supplies power to the rear view camera and gives

input of image signal.
