A broadcast receiver is provided for mounting on board a motor vehicle, whose control circuit is entirely electronic. The receiver comprises a case whose front face, accessible to the user, is free from unevennesses or appreciable projections and which presents an opaque appearance when the receiver is stopped. The front wall is formed by a plate made from a tinted transparent plastic material. It comprises four sensitive zones which are formed by metallizations on the rear face of the plate so as to form capacitive proximity sensor keys. The indication of the wave range is effected by selective illumination of zones comprising graduations and/or by means of a double seven-segment display.
