Abstract

본 발명은 자동차의 카 오디오 기능을 이용한 데이타의 무선 교신 및 데이타의 저장기능에 관한 것으로, 일반적으로 사용되고 있는 기존의 카오디오 회로는 단순히 수신 전용장치로서 소비자의 다양한 요구성향을 만족시키지 못하는 결함을 가지고 있었다. 이에 따라 본 발명은 상기와 같은 기존의 카 오디오 회로에 따르는 결함을 해결하고자. 카 오디오의 기존 기능에 데이타의 저장 및 무선 교신기능을 추가함으로써 사용자가 원하는 정보를 카 오디오에 기억시켜 놓을 수 있을뿐만 아니라 무선 교신 기능을 추가하여 메인 시스템과 데이타를 무선 교신함으로써 교통 상황의 보고는 물론 행선지의 교통 상황에 대한 정보를 수신할 수 있도록 함으로써 무선 전화기를 사용하지 않고도 이와 같은 기능을 수행할 수 있으며, 카 오디오의 기능도 동시에 즐길 수 있는 효과를 준다.The present invention relates to the wireless communication of data and the storage of data using the car audio function of a car, and the conventional car audio circuit which is generally used has a defect that does not satisfy various demands of consumers as a reception only device. there was. Accordingly, the present invention seeks to address the deficiencies associated with such conventional car audio circuitry. By adding data storage and wireless communication functions to the existing functions of car audio, users can not only store the information they want in car audio, but also add wireless communication function to wirelessly communicate data with the main system. Of course, by being able to receive information on the traffic conditions of the destination, it is possible to perform such a function without using a cordless phone, and the effect of car audio can be enjoyed at the same time.
