In this priority control, only one part 1100, 1201, 1202, or 1203 is selectively connected to the speaker unit 1300 / microphone unit 1400 through a predetermined switching circuit (not shown) 1201, 1202, and 1203 and the speaker unit 1300 / microphone unit 1400 are connected in parallel, but the volume of each input / output signal may be controlled according to the priority order .

As an example of the priority assignment, the priority control unit 1520 can assign the highest priority to the first Bluetooth module 1201 paired with the mobile communication terminal. That is, when the FRS communication is performed by the wireless communication unit 1100, the MP3 music is being listened through the Bluetooth module 1202, or the first Bluetooth module 1201 is connected to the navigation through the third Bluetooth module 1203, The volume of the part 1100, 1202, or 1203 that is currently being operated or automatically switched to be connected to the first Bluetooth module 1201 is automatically lowered to the mobile communication terminal, . After that, when the call disconnect signal is received in the first Bluetooth module 1201, it can be restored to the previous communication or performing state.

As another example of the priority assignment, when the first Bluetooth module 1201 is not paired with the mobile communication terminal or the telephone conversation of the mobile communication terminal ends, the radio communication unit 1100 performing the FRS communication assigns the highest priority can do.
