Abstract:
An integrated circuit card type car audio system comprising:a comparator for comparing a password number stored in the integrated circuit card which is loaded on said car audio system with a reference password number;a mode select means for generating a general mode select signal or an integrated circuit card mode signal so as to select a general mode or an integrated circuit card mode of said car audio system when the stored password number in the integrated circuit card and the reference password number coincide with each other;a controller for receiving any of the mode select signals selected by the mode select means and generating a mode execute control signal according to the one mode signal selected, and discriminating whether the integrated circuit card is a corresponding card for performing functions of said system based on the comparison result of the comparator;an output circuit for outputting information to indicate whether the loaded integrated circuit card is a corresponding card for performing functions of said system according to the discriminating result from the controller; anda function circuit for executing any mode selected by the mode select means in response to the mode execute control signal generated by the controller.
