Hi,
I have a gps unit that sends 12v current to a audio buzzer when car exceeds certain speed.
Sometimes when the radio is on loud and the buzzer warning alarm is drowned out with music from the radio.
Just wondering how I can temporarily turn off the power to the radio/speakers when the gps unit sends 12v current to the buzzer alarm, and restore speaker volume again when the gps unit stops sending current to the buzzer (speed is reduced)?
Thanks
Aid
