AUDIO AND VISUAL SYSTEM (w/ Navigation System) Sound Signal Circuit between Radio Receiver and Stereo Jack Adapter

DESCRIPTION

The No. 1 stereo jack adapter assembly sends an external device sound signal to the radio receiver assembly through this circuit.

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