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, voice control, naviga-

tion, USB connection, DVD play, satellite radio and vehicle information functions.

• It is connected to ECM and unified meter and A/C amp. 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.

• Amp. ON signal, sound 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.

Rear display unit

• Rear display image is controlled by the serial communication from video distribu-

tor.

• RGB image signal is input from video distributor (RGB image and RGB area).
• Composite image signal [USB (video data), DVD and auxiliary images] is input

from the video distributor.

• Synchronize signal (HP, VP) is output to video distributor.
• It receives the DVD/AUX/USB sound signal from the AV control unit, and then

transmits it to the headphones.

• It operates by receiving the headphone ON signal from the video distributor.

Video distributor

• It receives the image signal from the AV control unit and then transmits it to the

rear display unit.

• It transmits headphone ON signal to rear display unit.

BOSE amp.

• Inputs sound signal from AV control unit, and outputs sound signal to each speak-

er.

• Input mode change signal from AV control unit.

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.

Front squawker

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

Rear squawker

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

Center speaker

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

Woofer

• Inputs power (woofer amp. ON) and 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 cable, 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 cable, and operation signal is transmitted

to AV control unit via AV communication.

• The disk ejection operating signal is performed by hardwire.

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.

Side camera RH

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

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

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

view monitor control unit.

Infrared LED
(Auxiliary lighting)

• It illuminates around the front RH wheel by the power supply from around view

monitor control unit to improve nighttime visibility of front-side view.

• The infrared LED is an invisible light ray.

Sonar control unit

• It is connected with around view monitor control unit via AV communication and

receives the sonar operation signal from around view monitor control unit.

• It transmits the sonar detection status to around view monitor control unit via AV

communication.

• It judges the warning level according to the signal from corner sensor.

Corner sensor

The obstacle distance is detected. The signal is transmitted to sonar control unit.

Steering switch

• Operations for audio, hands-free phone, voice control and navigation, etc. are pos-

sible.

• Steering switch signal (operation signal) is output to AV control unit.

Microphone

• Used for hands-free phone operation and voice recognition.
• Microphone signal is transmitted to AV control unit.
• Power (Microphone VCC) is supplied from AV control unit.

Auxiliary input jacks

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

GPS antenna

GPS signal is received and transmitted to AV control unit.
