Auxiliary Input Jack

INFOID:0000000010122517

• AUX jack is installed at the lower right of the instrument panel.

• Connection to an external audio device can provide sound output.

NOTE:

When connected to monaural mini-jack plug cable, sound may not

be output.

SD Card

INFOID:0000000010122518

• Map data is memorized in an 8 GB SDHC

card.

• Map data is sent to the AV control unit from the SD slot.

NOTE:

*SDHC: Abbreviation of SD High-Capacity. It is the upper level standard of the SD memory card. A large quan-

tity of data can be memorized, and the transfer speed of data is high.

TCU Input Signal

MULTI AV SYSTEM : System Description

INFOID:0000000010122520

• AV control unit is connected to the following parts. It performs power supply, signal input and communica-

tion, and it controls the multi-AV system.

- GPS antenna

- Radio antenna (radio antenna amplifier)

- Rear view camera

- USB connector

- Auxiliary input jack

- BCM

- VCM

- Combination meter

- Steering switch

- Multifunction switch

- Microphone

- TCU

- Speakers

- Vehicle signals (reverse signal, vehicle speed signal and illumination signal)

• Data of external device connected to the USB connector is played and transferred.

• When the selector lever is placed in R (reverse), power is supplied to the rear view camera. The camera

image signal supplied by the rear view camera is input to the AV control unit. The AV control unit displays the

rear view camera image on the display.

• Dimming signal is input from BCM to adjust the brightness of the display.

SYSTEM

COMMUNICATION SIGNAL

AV control unit is connected to TCU via USB communication, and it receives the Telematics information

received by TCU and gives the display and sound output. Telematics operation signals and sound signals are

also sent to TCU.

Auto light adjustment function

Auto light adjustment function automatically dims/brightens the display according to the ambient light when the

lighting switch is in the 1st or 2nd position. Whether or not the display is dimmed when the lighting switch is in

the 1st position or 2nd position is determined by the output condition of the dimming signal output from the

BCM to the AV control unit. Even if the lighting switch is in the 1st position or 2nd position, the display may not

be dimmed depending on the ambient light sensed by the auto light sensor. For details, refer to

INL-11, "ILLU-

MINATION CONTROL SYSTEM : System Description"

CAN COMMUNICATION

• AV control unit is connected via CAN communication, receives data signal from VCM and combination

meter, and indicates power consumption information, etc. on the display based on the information obtained.

• 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 and sends signals necessary for timer charge and A/C-heater timer operation with

VCM via CAN communication.

Energy Flow Display Function

The AV control unit receives data signals from the VCM and combination meter via CAN communication and

computes each value using the obtained information to display it.

Vehicle Setting Function

The AV control unit transmits and receives data signals via CAN communication with the BCM, allowing the

following vehicle settings.

• To turn on the automatic interior room lamp (ON/OFF) when the door is unlocked

• To adjust the auto light sensitivity (+/

−)

• To operate the intermittent wiper linked with the vehicle speed (ON/OFF)

• Vehicle setting initialization

NOTE:

The setting items vary depending on the vehicle specification

TYPE OF VOICE SIGNAL

Reception Voice Signal

• Hands-free phone reception voice is output from the cellular phone through the AV control unit to the front

speaker via Bluetooth

communication.

• If the hands-free phone is used while the audio is ON and/or the voice guidance is being output, these

sounds are muted and only the reception voice is output.

Speech Sound Signal

Hands-free phone speech sound is transmitted from the microphone via the AV control unit and Bluetooth

communication to the cellular phone.

Display function

Receiving signal (transmit unit)

Display method

Instantaneous power
consumption display

• Battery consumption monitor signal

(VCM)

• Vehicle speed signal (combination

meter)

Computes the instantaneous power consumption using the vehicle
speed and battery consumption monitor signals, and displays the in-
stantaneous power consumption bar.

Possible driving dis-
tance display

• Possible driving distance signal

(Combination meter)

Displays a possible driving distance, based on a possible driving
distance signal. When the meter indication of a possible driving dis-
tance is “----”, it is displayed by “

”on the NAVI screen.

Data is retained even with the power switch OFF.

Average power con-
sumption display

• Battery consumption monitor signal

(VCM)

• Vehicle speed signal (combination

meter)

Computes the average power consumption using the battery con-
sumption monitor and vehicle speed signals, and displays it.
The average power consumption is displayed only when 30 sec-
onds have elapsed and the vehicle has been driven 500 m after the
average power consumption was reset.
Data is retained even with the power switch OFF.
