Part name 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.

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.
