A remote control device in a vehicle is provided in proximity of a
driver's seat such that an operation unit of the remote control device is
manually rotated and pressed by a hand of a driver in a driver's seat. A
case of the remote control device contains vibrators to vibrate left and
right sides of the remote control device. A navigation device is
connected to a control unit of the remote control device. When a position
of the vehicle approaches a specified guidance point during route
guidance, the navigation device outputs a guidance signal (left-turn or
right-turn instruction) to the control unit. When supplied with the
guidance signal, the control unit controls driving of the vibrators to
vibrate the remote control device based on the guidance signal.
