Sound Signal Circuit between Navigation Receiver Assembly and Stereo Jack Adapter: Description

The No. 1 stereo jack adapter assembly sends an external device sound signal to the navigation receiver assembly via the sound signal 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.
