  Visual Mute Signal Circuit between Navigation Receiver Assembly and Multi-display

DESCRIPTION

The multi-media module receiver assembly sends a visual mute signal to the multi-display assembly. As a result, a black screen is displayed when the screen changes so that noise and distorted images are not displayed.

When an open exists in the circuit, noise and distorted images will be displayed instead of a black screen.

When a short exists in the circuit, even though the multi-display assembly is operating normally, noise and distorted images will be displayed (black screen will not be displayed) during screen changes or the black screen will always be displayed.
