Mute Signal Circuit Between Navigation Receiver Assembly And Stereo Component Amplifier: Description

This circuit sends a signal to the stereo component amplifier assembly to mute noise. Because of that, the noise produced by changing the sound source is muted.

If there is an open in the circuit, noise can be heard from the speakers when changing the sound source.

If there is a short in the circuit, even though the stereo component amplifier assembly is functioning normally, no sound or only an extremely small sound can be heard.
