1. A motor vehicle radio with an automatic volume control device, to which is fed a speed signal detected by a speed sensor and which delivers a volume signal associated with the detected speed signal, and with a manual volume-setting device which generates a volume signal corresponding to the volume which has been set, characterized by the fact that a two-position switch (16) is provided for selectively transmitting the volume signal of the automatic volume control device (20) or of the manual volume-setting device (14) to an output stage (12) of the radio (10) which feeds loudspeakers (13);

  • and a storage and control circuit (23) which includes a memory in which the volume signal corresponding to the adjusted volume can be stored when the manual volume-setting device (14) is switched on following a detection signal for a desired vehicle speed.
