Component Description

Part name Description
AV control unit
  • Integrates hard disk drive (HDD) allowing map data to be stored. (Except for Mexico)
  • 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 signals from the AV control unit.
  • The AV control unit includes the audio, hands - free phone, voice control, navigation, USB connection, DVD play, satellite radio and vehicle status functions.
  • It is connected to each control unit via CAN communication to obtain necessary information for the vehicle information function.
  • It inputs the dimmer signals that are required for the display dimming control.
  • It inputs the signals for driving status recognition (vehicle speed, reverse and parking brake).
  • The RGB digital image signal and composite image signal are output to display unit.
  • It is receives an intelligent key recognition signal necessary for the intelligent key interlocking function from BCM via a hard wire
  • Update of map data is performed with the DVD - ROM.
Display unit
  • Display image is controlled by the serial communication from AV control unit.
  • The RGB digital image signal and composite image signal are input to display 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 directly.
BOSE amp.
  • BOSE amp. include active noise control system and AudioPilot® 2 noise compensation technology. (BOSE stereo sound system models)
  • BOSE amp. include active noise control system, AudioPilot® 2 noise compensation technology and BOSE® Centerpoint® 2 function. (BOSE® Studio Surround® sound system models)
  • Generates an antiphase sound weakening interior engine booming noise, mixes the antiphase sound with a sound signal transmitted from the AV control unit, and transmits the mixed sound signal to each speaker.
  • Input microphone signal transmitted from front microphone (for AudioPilot® 2 noise compensation technology).
  • Input microphone signal transmitted from both front and rear microphone (for active noise control system).
Front door woofer

Preset switch
  • Operation panel is equipped with the centralized switch where audio, 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 superimposes the images from each camera and outputs them to display unit.
  • Superimpose the guiding line, predicted course line and sonar indicator to the camera image that outputs to 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 sonar information from sonar control unit via CAN 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.
