System DiagramINFOID:0000000003882699
NOTE:
 The name MULTIFUNCTION SWITCH indicates the integration of PRESET SWITCH and MULTIFUNCTION
SWITCH virtually.
 A radio antenna base integrated with radio antenna amp. is adopted.
 Woofer illustrated in the above figure, integrates two woofers and a woofer amp.
System DescriptionINFOID:0000000003882700
Multi AV system means that the following systems are integrated.
 AV control unit controls 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, combination
meter. It computes and displays fuel economy information value with the obtained information. Transmitting/
receiving of data signal is performed by BCM. Also, it transmits the required signal of vehicle setting and
receives the response signal.

System DescriptionINFOID:0000000003882704
The audio system is equipped with following function. Each function can be operated with the multifunction
switch, preset switch, rear control switch or steering switch. It indicates the operation status of AUDIO to the
display unit.
FUNCTION DESCRIPTION
Operating Signal
Operation of the audio system can be performed via the multifunction switch, preset switch, rear control switch
or steering switch.
 Operating signal is transmitted to AV control unit via AV communication when it is operated by multifunction
switch, preset switch or rear control switch. The CD ejection operating signal is performed by hard-wire.
 Operating signal is transmitted to AV control unit with steering switch signal when it is operated by steering
switch.
Screen Display
 The display switching of the screen is performed by the communication signal between the display unit and
the AV control unit.
 The image signal to display operating condition is performed by 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 glass antenna, next it is amplified by antenna amp., and finally it is input to
AV control unit. The FM sub antenna is installed on the rear window glass and the AV control unit is
received.
 Sound signal is input to AV control unit, and AV control unit outputs to each speaker.
CD Mode
 CD function is built into AV control unit.
 AV control unit outputs sound signal to each speaker when CD is inserted to AV control unit.

CAMERA IMAGE OPERATION PRINCIPLE
 Power is supplied to rear view camera from camera control unit and the rear view camera outputs the cam-
era image to camera control unit when selector lever is set to reverse position and the reverse signal on
camera control unit is input.
 Camera control unit superimposes the guiding line and predicted course line to the image from rear view
camera and outputs to display unit. In this case, the reverse signal is also input to AV control unit. Therefore,
AV control unit recognizes the selector lever as in the reverse position. And then AV control unit switches the
image displayed by the communication signal between AV control unit and display unit with the camera
image.
 AV control unit outputs camera image signal that is inputted from camera control unit to display unit.
 Camera control unit controls the direction and distance of predicted course line according to the sensor sig-
nal from steering angle sensor.
 AV control unit determines whether rear view camera is equipped or not, based on the presence of camera
connection recognition signal. It switches to rear view monitor image at the time of reverse signal input when
rear view camera is equipped.
