• The base unit controls the AM/FM tuner, upper/lower modules, and externally extended unit (e.g. CD changer).
• An auto level control (ALC) function that controls speaker volume according to vehicle speed has been adopted.
• For drive information system (DIS) equipped vehicles, a CAN communication control circuit is included in the base unit. The base unit receives, using the CAN system, the DIS display signal from the instrument cluster, and converts it to a signal sent to the information display (See DRIVE INFORMATION SYSTEM OUTLINE.)
