Embodiment Construction

[0020] The present invention proposes a solution for simplifying the interface between the vehicle original audio magnetic head unit and the driver's desired built-in or external multimedia unit.

[0021] As mentioned above, when the present invention removes the car audio head unit panel part from the center fascia (center fascia) of a general vehicle and installs the multimedia unit in the space formed, it is not necessary to use a driving computer similar to the original audio system. The independent intermediate medium can be operated only by connecting the original audio head unit and wiring, so it can solve the problems of installation convenience and operability of the multimedia unit.

[0022] In order to make it easy for those skilled in the technical field of the present invention to implement, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, the present invention is capable of many varia...

Abstract

The invention provides a multimedia system and a method for interfacing between a multimedia unit and an audio head unit. When the multimedia unit is installed in space formed by detaching a vehicle-mounted loudspeaker host panel part from a central riggle of a conventional vehicle, an independent middle media such as a travelling computer used for operating the original loudspeaker is not used and the multimedia unit can be operated only through connection between an original audio head unit and wiring harness, so that the problem in installation convenience and operability of the multimedia unit can be solved.

Description

technical field [0001] The invention relates to a multimedia system and an interface mode between a multimedia unit and an audio magnetic head unit. Background technique [0002] Generally, the information display unit located on the main unit panel of the car audio has the function of visually displaying various information related to the operating state of the audio to the driver. The information conveyed by this information display unit is mainly related to the operating status of radio and CD players. However, recently, various multimedia functions such as reproduction of audio sources on MP3, CD, and IPod; Hands Free and voice recognition using Bluetooth have begun to be adopted. Therefore, the combination of information that needs to be displayed has become more diverse. In addition, in order to allow users to operate these diverse multimedia functions, the host panel of the car audio system needs to be equipped with a plurality of composite function operation keys. ...
