AV CONTROL UNIT
• Integrates HDD (hard disk drive) 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 means of communication. It operates each system according to com-
munication signals from the AV control unit.
• The AV control unit includes the audio, hands-free phone, voice control, navi-
gation, and vehicle information functions.
• It is connected to ECM and unified meter and A/C amp. via CAN communica-
tion to obtain necessary information for the vehicle information function.
• It inputs the automatic brightness ON/OFF signals that are required for the dis-
play dimming control.
