Sound Signal Circuit between Stereo Component Tuner Assembly and Multi-media Interface ECU (TO 12/2010): Description

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

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 multi-media interface ECU, stereo component amplifier assembly, navigation receiver assembly or speakers.
