Hereinafter, an apparatus for preventing malfunction of an IPOD player according to an embodiment of the present invention will be described with reference to FIGS. 1 to 4. 1 is a block diagram illustrating a malfunction prevention apparatus of an IPOD player according to an embodiment of the present invention, Figures 2 to 4 are exemplary diagrams for explaining the malfunction prevention apparatus of the IPOD player.

As shown in FIG. 1, the apparatus for preventing malfunction of the IPOD player of the present invention includes a switch 110 and a cable detector 120.

The switch 110 connects the cable connection terminal 210 connected to the cable to the digital signal processor 220 or the analog signal processor 230 according to the detection signal. For example, when the switch 110 receives a detection signal for connecting the cable connection terminal 210 to the digital signal processor 220, the switch 110 connects the cable connection terminal 210 to the digital signal processor 220, and the cable connection terminal. When the detection signal for connecting the 210 to the analog signal processor 230 is received, the cable connection terminal 210 is connected to the analog signal processor 230.

The switch 110 sets the initial connection of the cable connection terminal 210 to the analog signal processor 220.

Meanwhile, the digital cable transmits a digital signal to the digital signal processor 220, that is, the USB process through the USB communication method, and the analog cable delivers an analog signal to the analog signal processor 230, that is, the UART process through the UART communication method. do.

As shown in FIG. 2, when an analog IPOD dedicated cable to which an IPOD player is connected is inserted into a vehicle multi-terminal, that is, a cable connection terminal 210, there may be no response from the vehicle multimedia device or the IPOD player may not operate.

In this case, the cable detection unit 120 detects the type of cable connected to the cable connection terminal 210, and if the detected cable type is included in the dedicated cable type of the IPOD player, whether the dedicated cable type is digital or analog. Accordingly, a detection signal corresponding thereto is output. That is, the cable detector 120 outputs a detection signal for connecting the cable to the digital signal processor 220 when the dedicated cable type is a digital cable, and if the cable is an analog cable, the cable to be connected to the analog signal processor 230.
