Part name Description
NAVI CONTORL UNIT Map data can be read from the map DVD-ROM by installing map DVD-ROM.
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 NAVI control unit.
The NAVI control unit includes the audio, hands-free phone, navigation, and
vehicle information functions.
It is connected to ECM and combination meter via CAN communication to ob-
tain necessary information for the vehicle information function.
It inputs the illumination signals that are required for the display dimming con-
trol.
It inputs the signals for driving status recognition (vehicle speed, reverse and
parking brake).
