System Description

INFOID:0000000003356749

MULTI AV system means that the following systems are integrated.

• AV control unit functions 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 signals from ECM and combina-

tion meter. It computes and displays fuel economy information value with the obtained information. Transmit-
ting/receiving of data signals are performed by BCM. Also, it transmits the required signal of vehicle setting
and receives the response signal.

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

signal of display and display control and receives the response signal from front display unit. It is also con-
nected with satellite radio by serial communication, transmits the operating signal and receives the display
signal.

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

AV-83, "CONSULT-III Function (MULTI AV)"

• On board self-diagnosis: refer to

for on board self-diagnosis.

AUXILIARY INPUT SYSTEM

• Image and sound can be output from an external device by connecting a device with auxiliary input jacks.
• Operation can be performed with multifunction switch and steering switch. Multifunction switch transmits

operation signal to AV control unit by AV communication.

Without DVD Entertainment System

• The AUX image signal is input from the auxiliary input jacks to the AV control unit. The AV control unit out-

puts AUX image signal to the front display unit.

System Description

CAMERA IMAGE OPERATION PRINCIPLE

• Power is supplied to rear view camera from camera control unit and outputs camera image signal to camera

control unit when selector lever is set to R position and the reverse signal on camera control unit is input.

• Camera control unit synthesizes guide lines and possible route lines with camera image signal from rear

view camera, and transmits camera image signal to the AV control unit. In this case, since the reverse signal
is also input to AV control unit, the AV control unit recognizes that the selector lever is in the R position, and
it switches communication signal between AV control unit and front display unit, and image that is displayed
on the front display unit by RGB image signal with rear view monitor image. In addition, possible route lines
are controlled by original sensor signal from steering angle sensor.

• The AV control unit determines whether rear view camera is equipped or not, based on the presence of cam-

era connection recognition signal. It switches to rear view monitor image at the time of reverse signal input
when it is equipped.

• Warning message under the rear view monitor display is described by AV control unit.
• AV control unit is connected in communication with camera control unit and front display unit, and it controls

operation of rear view monitor system.
