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
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.
