Sound Signal Circuit between Stereo Component Tuner Assembly and Multi-media Interface ECU: Description

The stereo component tuner assembly sends satellite radio sound signals to the multi-media interface ECU through this circuit.

The sound signal that has been sent is amplified by the stereo component amplifier, 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, navigation receiver assembly or speakers.
