An onboard apparatus comprising a connection portion, a control block, and a bus switch is provided. The connection portion connects with an external device mounted to a vehicle, and includes at least a data terminal to input and output a communication data and a control terminal to output a communication availability signal that indicates communication is available or not. The control block performs data communication with the external device, which is connected to the connection portion. The bus switch, according to a permission signal, changes a non-conduction state to a conduction state of a transmission path from the control block to the data terminal. A signal level of the permission signal varies when an output of the control block is stabilized after the onboard apparatus starts.
