Sound Signal Circuit between Navigation Receiver Assembly and Multi-media Interface ECU: Description

The multi-media interface ECU sends USB audio sound signals and satellite radio sound signals to the navigation receiver assembly through this circuit.

The sound signal that has been sent is amplified by the stereo component amplifier assembly, and then is sent to the speakers.

If there is an open or short in the circuit, sound cannot be heard from the speakers even if there is no malfunction in the stereo component amplifier assembly, navigation receiver assembly or speakers.
