mute on car kit
Does anyone know how to make mute radio from XDA.
In the connector I have not found any signal to mute the radio.
I have not any idea, how to do in the car kit.
Problem is, when I listen some radio station and somebody call me, I need to turn off the radio automaticly when I pick up the phone or when I dialing, like in real car kit.
Is in the XDA some signal to do it, or just car kit for XDA check input audio signal from the connector and when it will be some sound automaticly mute the radio?
Thanks for help.
