2001 Cadillac Deville Audio Mute

Is there a wire I can use on the radio for my nokia cark-91 Hands free kit? 2001 Deville. Thanks guys.

There isn't a mute line for this radio. The radio uses a data line that sends messages to the amp. The only thing you might try is to use relays to open the audio outputs from the headunit to the amp. You may get a noise problem on the audio system though, as these lines are a preamp signal and use shielded cables. It's easier to just turn the radio down manually or via the steering wheel radio controls.sparky
