PART NAME DESCRIPTION

Part name Description
AV CONTROL UNIT
  • 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.
  • AV control unit includes audio function and vehicle information function.
  • 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 is connected to BCM via CAN communication transmitting/receiving for the vehicle settings function.
  • It inputs the illumination signals that are required for the display dimming control.
  • It inputs the signals for driving status recognition (vehicle speed, reverse and parking brake).
  • Auxiliary image signal is input from the auxiliary input jacks.
DISPLAY UNIT
  • Display image is controlled by the serial communication from AV control unit.
  • RGB image signal is input from AV control unit (RGB, RGB area and RGB synchronizing).
