Abstract
In a vehicle audio apparatus, the detection switch is turned off when the lock claw is released from the lock-claw holder to open the front panel. The bi-directional switches are thereby turned off, disconnecting the data lines SD+and SD− between the USB interface unit of the main unit and the USB socket of the front panel. Thereafter, the front panel is opened, releasing the connector () from the connectorand ultimately disconnecting the power-supply lines (VBUS and GND). Hence, the vehicle audio apparatus is prevented from being abruptly disconnected from the power supply. This prevents the data stored in the USB memory from being destroyed.
