In a vehicle onboard apparatus, a connection detection function expands a specific file and activates an SSH connection function when a USB memory storing a specific file is connected, and thereby enables access to an application function from a general-purpose OS function during a period in which the USB memory is connected. A disconnection detection function stops the SSH connection function and deletes the SSH connection function when the USB memory is disconnected, and thereby disables access to the application function from the general-purpose OS function during a period in which the USB memory is not connected.
