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

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.
