MULTI AV SYSTEM : System Description

INFOID:0000000005527810

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 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. Trans-
mitting/receiving of data signal is performed by BCM. Also, it transmits the required signal of vehicle setting
and receives the response signal.

SYSTEM

AV-19

< SYSTEM DESCRIPTION >

[WITHOUT NAVIGATION]

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

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

AUDIO FUNCTION

The audio system is equipped with the following functions. Each function is operated with multifunction switch,
preset switch, steering switch. Operation status of audio is indicated at front display.

Operating Signal

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 ejection operating signal is performed by hardwire.

• Operating signal is transmitted to AV control unit with steering switch signal when it is operated by steering

switch.

Screen Display

• Switching of front display is performed with serial communication between front display unit and AV control

unit.

• The image signal to display operating condition is performed with RGB image signal, RGB area signal and

RGB image synchronizing signal.

AM/FM Radio Mode

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

trol unit. Audio signal is input to BOSE amp., and BOSE amp. outputs 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 antenna and transmitted to AV control unit. AV control

unit outputs sound signal (satellite radio) to BOSE amp. The signal is also outputted from BOSE amp. to
both woofer and each speaker.

CD Mode

• CD function is built into AV control unit.
• AV control unit outputs audio signal to BOSE amp., and BOSE amp. outputs to each speaker when CD is

inserted to AV control unit.

Music Box Mode

• Music CD data is stored on flash memory that is built into AV control unit, and it can be played.
• AV control unit outputs music (sound signal) that is stored on flash memory to BOSE amp., and BOSE amp.

outputs to each speaker.

USB Connection Function

• iPod or music files in USB memory can be played.
• iPod sound signals are transmitted from USB connector to the AV control unit and to each speaker.
• iPod

is recharged when connected to USB connector.

iPod

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

NOTE:
Use the enclosed USB harness when connecting iPod

to USB connector.

Driver's Audio Stage

• Driver's Audio Stage controls the speaker's output characteristic by BOSE amp. so that the driver's seat is to

be the center of sounds.

SYSTEM

• ON/OFF signals of Driver's Audio Stage are transmitted from AV control unit to BOSE amp. using mode

change signal.

HANDS-FREE PHONE SYSTEM

• TEL adapter unit is controlled with AV communication from AV control unit.
• The connection between cellular phone and TEL adapter unit is performed with Bluetooth

™

communication.

• The voice guidance signal is input from the TEL adapter unit to the AV control unit and output via BOSE

amp. to the front speaker when operating the cellular phone.

• TEL adapter unit has the on board self-diagnosis function. Refer to

AV-34, "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 via BOSE amp. to front speaker.

AUXILIARY INPUT FUNCTION

• Image and sound can be output from an external device by connecting a device with auxiliary input jacks.
• AUX image signals are transmitted to the front display unit through AV control unit.
• AUX sound signals are transmitted to each speaker through AV control unit and BOSE amp.

REAR VIEW MONITOR FUNCTION

• The AV control unit supplies power to the rear view camera when receiving a reverse signal.
• The rear view camera transmits camera images to the AV control unit when power is supplied from the AV

control unit.

• The AV control unit transmits a warning message, fixed guide lines, and predictive course lines to the front

display unit by RGB image signals. Rear view monitor images are displayed by combining the RGB image
signals and the camera image signals from the rear view camera.

• Predictive course lines are controlled by a steering angle sensor signal received the AV control unit via CAN

communication.

VEHICLE INFORMATION FUNCTION

• Status of audio, climate control system, fuel economy and maintenance are displayed.
• AV control unit displays the fuel consumption status while receiving data signal through CAN communication

from ECM, unified meter and A/C amp.

• AV control unit is connected to BCM via CAN communication transmitting/receiving for the vehicle settings
