DESCRIPTION
The No. 1 stereo jack adapter assembly sends the sound signal from an external device to the navigation receiver assembly via 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, DCM (telematics transceiver)*1 or speakers.
