Motor vehicle radio with an automatic volume control device
First Claim
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.

Abstract
The invention relates to a motor vehicle radio with an automatic volume control device (20) and a manual volume-setting device (14). The automatic volume control device (20) is fed with a speed signal detected by a speed sensor and delivers a volume signal associated with the detected speed signal. The manual volume-setting device (14) generates a volume signal corresponding to the volume which has been set. A two-position switch (16) is provided for selectively applying the volume signal from the automatic volume control device (20) or from the manual volume-setting device (14) to an output stage (12) which feeds the loudspeakers (13). When the manual volume-setting device (14) is switched on, following a detection signal for a desired vehicle speed, the volume signal corresponding to the volume which has been set can be stored in a storage and control circuit (23) of the automatic volume control device (20).
