Abstract: A portion of the instrument panel which is adjacent to the steering wheel is protruded and in which portion a radio receiving device is fitted which includes station-number and frequency indicator means and control means for station selection and frequency adjustment. The indicator means are arranged in the front face of the protruded panel portion so as to enable the driver readily to take the indicator readings without the need of shifting his line of sight to any substantial extent. The control means are arranged in the protruded panel portion sidewise thereof, including, among others, a single control knob arranged in a position to be readily reached by the driver's hand for controlling operation.
