A vehicle-mounted device control system includes a first vehicle-mounted device, a second vehicle-mounted device, and a control unit connected to the first vehicle-mounted device and the second vehicle-mounted device. The control unit includes signal transmission means that transmits a predetermined signal to the first vehicle-mounted device, cooperative control means that performs cooperative control in which the second vehicle-mounted device is controlled using information used by the first vehicle-mounted device when the first vehicle-mounted device responds to the predetermined signal, and alternative control means that performs alternative control in which the second vehicle-mounted device is controlled without using information, used by the first vehicle-mounted device, when the first vehicle-mounted device does not respond to the predetermined signal.
