NAVIGATION SYSTEM	System Description
AUDIO SYSTEM	System Description
VEHICLE INFORMATION SYSTEM	Status of audio, climate control system, fuel economy, tire pressure, maintenance and navigation is displayed. AV control unit displays the fuel consumption status while receiving data signal through CAN communication from ECM, combination meter. AV control unit displays the tire pressure status while receiving data signal through CAN communication from low tire pressure warning control unit. AV control unit is connected to BCM via CAN communication transmitting/receiving for the vehicle settings function.
HANDS‐FREE PHONE SYSTEM	Refer to the following “HANDS‐FREE PHONE SYSTEM”.
VOICE RECOGNITION SYSTEM	Refer to the following “VOICE RECOGNITION SYSTEM”.
TOUCH PANEL SYSTEM	Refer to the following “TOUCH PANEL SYSTEM”.
MULTI FUNCTION METER SYSTEM	Refer to the following “MULTIFUNCTION METER SYSTEM”.

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.
The AV control unit is connected with CAN communication line and receives data signals from the ECM, combination meter, TCM, AWD control unit, A/C auto amp., ABS actuator and electric unit (control unit), steering angle sensor and low tire pressure warning control unit. Using the obtained information, it computes values for the display items relating to the fuel consumption information, multifunction meter, and tire pressure information and displays them.
AV control unit is connected with display and serial communication, and it transmits the required signal of display and display control and receives the response signal from display. Also, it is connected with satellite radio by serial communication, and it transmits the operating signal and receives the display signal.
The AV control unit, which has the vehicle setting function, transmits and receives data on vehicle setting condition via CAN communication with the BCM.

NOTE：
AV control unit can perform CONSULT-III self-operating function and on board self-diagnosis.

CONSULT-III self diagnosis: Refer to CONSULT-III Function.
On board self diagnosis: Refer to Diagnosis Description.

HANDS‐FREE PHONE SYSTEM

Hands‐free communication can be operated by connecting using Bluetooth^TMcommunication with cellular phone.
Operation is performed by steering switch and multifunction switch, and operating condition is indicated on display.
Guide sound that is heard during operation is input from AV control unit to BOSE amp., and is output from door speaker.

When a call is originated

Spoken voice sound output from the microphone (Mic. Signal) is input to AV control unit. AV control unit outputs to cellular phone with Bluetooth^TM 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 door speaker, and the signal is input to BOSE amp. via AV control unit by establishing Bluetooth^TM communication from cellular phone.

VOICE RECOGNITION SYSTEM

Each operation of multi AV system can be performed by inputting sound to microphone.
Start of sound recognition system can be performed by steering switch.

TOUCH PANEL SYSTEM

Each operation of multi AV system can be performed by directly touching a display.

MULTIFUNCTION METER SYSTEM

Multi function meter system can be performed with multi function switch.

To inform the user of the most suitable usage of the high-performance vehicle, the mechanical information display function, driving assist display function, gear and fuel consumption display function, and driving history information display function are adopted.
