Mute Signal Circuit Between Stereo Component Amplifier and Telematics Transceiver

NAVIGATION / MULTI INFO DISPLAY: NAVIGATION SYSTEM (w/ USB Audio System): Mute Signal Circuit between Stereo Component Amplifier and Telematics Transceiver
- Mute Signal Circuit between Stereo Component Amplifier and Telematics Transceiver

DESCRIPTION

The telematics transceiver sends a mute signal to the stereo component amplifier assembly.

The stereo component amplifier assembly controls the volume according to the mute signal from the telematics transceiver.
