FIELD: electricity.
SUBSTANCE: when controlling the radio module of the vehicle, the starter relay signal is received from the power unit by control unit (105) corresponding to the engine start request. Mute the sound of the audio device coupled to the radio module (115). Deferred auxiliary equipment signal is received from the second control unit indicating a delayed initiation of the auxiliary equipment. Turn on the sound of the audio device in response of receiving a deferred signal from the auxiliary equipment. Vehicle radio control system is also proposed.
EFFECT: it is achieved the mute of the sound of the audio device when the driver starts the engine to avoid unpleasant noises from the speakers.
