MULTIMEDIA SYSTEM AND METHOD FOR INTERFACING BETWEEN MULTIMEDIA UNIT AND AUDIO HEAD UNIT

摘要

Provided are a multimedia system and a method of interfacing a multimedia unit and an audio head unit. The present invention relates to a method in which an audio front panel of a vehicle is detached from a center fascia of the vehicle to secure a free space, and then, in mounting a multimedia unit in the secured free space, the multimedia unit is operably connected to a pure audio head unit through only a wiring without a separate intermediate medium, such as a trip computer, for manipulating the pure audio head unit of the vehicle, and overcomes limitations of the mounting convenience and manipulability of the multimedia unit.
