SYSTEM

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 and combination

meter, and computes and displays fuel economy information value with the obtained information. Transmit-
ting/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.

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 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 display is performed with serial communication between 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.
• AM/FM radio wave is received by rod 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. The FM

sub antenna is installed on the back door window glass.

• AV control unit outputs audio signal to BOSE amp. The signal is also outputted from BOSE amp. to woofer

and 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 (antenna base) and transmitted to AV

control unit via satellite radio tuner.

• AV control unit outputs audio signal (satellite radio) to BOSE amp. The signal is also outputted from BOSE

amp. to woofer and each speaker.

CD Mode

• CD function is built into AV control unit.
• AV control unit outputs audio signal to BOSE amp. The signal is also outputted from BOSE amp. to woofer

and each speaker when CD is inserted to AV control unit.

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 to the front
