Description

AV control unit

• Integrates hard disk drive (HDD) allowing map data and music data to be stored.
• It is the master unit of the MULTI AV system, and it is connected to each control

unit by communication. It operates each system according to communication sig-
nals from the AV control unit.

• The AV control unit includes the audio, hands-free phone, navigation, USB con-

nection, DVD play and vehicle information functions.

• It is connected to ECM and combination meter via CAN communication to obtain

necessary information for the vehicle information function.

• It inputs the illumination signals that are required for the front display dimming con-

trol.

• It inputs the signals for driving status recognition (vehicle speed, reverse and park-

ing brake).

• The RGB digital image signal and composite image signal are output to front dis-

play unit.

• Switches image and sound output to video distributor, inputting image switch sig-

nal from headrest display unit via AV communication.

• Amp. ON signal and mode change signal transmitted to BOSE amp.
• Update of map data is performed with the DVD-ROM.

Front display unit

• Front display image is controlled by the serial communication from AV control unit.
• RGB digital image signal is input from AV control unit.
• Composite image signal is input from AV control unit.
• Camera image signal is input from around view monitor control unit.
• Touch panel function can be operated for each system by touching a display di-

rectly.

Headrest display unit

• Composite image signal [USB (video data), DVD and auxiliary input images] is in-

put from the video distributor.

• It receives the DVD/AUX/USB sound signal from the video distributor, and then

transmits it to the headphones.

• Outputs image switch signal to video distributor via hard wire, according to rear

seat remote controller operation.

• Outputs image switch signal to AV control unit via AV communication, according to

rear seat remote controller operation.

Video distributor

• It receives the image signal and sound signal from the AV control unit and then

transmits it to the headrest display unit.

• It receives the image signal and sound signal from the auxiliary input jacks and

then transmits it to the headrest display unit.

• Switches image and sound output to headrest display unit, inputting image switch

signal from headrest display unit via hard wire.

Front auxiliary input jacks

Image signal and sound signal of auxiliary input is transmitted to AV control unit.

Rear auxiliary input jacks
(Mobile entertainment system)

Image signal and sound signal of auxiliary input is transmitted to video distributor.

BOSE amp.

Inputs sound signal from AV control unit, and outputs sound signal to each speaker.

Front door speaker

• Outputs sound signal from BOSE amp.
• Outputs high, mid and low range sounds.

Rear door speaker

• Outputs sound signal from BOSE amp.
• Outputs high, mid and low range sounds.

Squawker

• Outputs sound signal from BOSE amp.
• Outputs high and mid range sounds.

Rear door tweeter

• Outputs sound signal from BOSE amp.
• Outputs high range sounds.

Roof speaker

• Outputs sound signal from BOSE amp.
• Outputs high and mid range sounds.

Center speaker

• Outputs sound signal from BOSE amp.
• Outputs high and mid range sounds.

Woofer

• Outputs sound signal from BOSE amp.
• Outputs low range sounds.

Multifunction switch

• Operation panel is equipped with the centralized switch where audio, auxiliary in-

put and navigation, etc. operations are integrated.

• Connected with preset switch via hardwire and operation signal is transmitted to

AV control unit via AV communication.

Preset switch

• Operation panel is equipped with the centralized switch where audio and air con-

ditioner, etc. operations are integrated.

• Connected with multifunction switch via hardwire, and operation signal is transmit-

ted to AV control unit via AV communication.

• The disk ejection operating signal is performed by hardwire.

Steering switch

• Operations for audio, hands-free phone and navigation, etc. are possible.
• Steering switch signal (operation signal) is output to AV control unit.

Around view monitor control unit

• It supplies power to front camera, rear camera, and side camera. And then it su-

perimposes the images from each camera and outputs them to front display unit.

• Superimpose the guiding line, predicted course line and sonar indicator to the

camera image that outputs to front display unit.

• It performs the reception/transmission of communication signal with each camera.
• It transmits the sonar operation signal from sonar control unit and receives the so-

nar information from sonar control unit via AV communication.

• It transmits the information received/transmitted with sonar control unit via AV

communication to AV control unit.

Front camera

• It inputs the power supply from around view monitor control unit and outputs the

image of the vehicle front to around view monitor control unit.

• It performs the reception/transmission of the communication signal with around

view monitor control unit.

Rear camera

• It inputs the power supply from around view monitor control unit and outputs the

image of the vehicle rear to around view monitor control unit.

• It performs the reception/transmission of the communication signal with around

view monitor control unit.

Side camera LH

• It inputs the power supply from around view monitor control unit and outputs the

image of the vehicle LH to around view monitor control unit.

• It performs the reception/transmission of the communication signal with around

view monitor control unit.
