Land Cruiser URJ200 URJ202 GRJ200 VDJ200 - AUDIO / VIDEO
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 the sound signal from an external device to the multi-media module receiver assembly through this circuit.
The sound signal that has been sent is amplified by the stereo component amplifier assembly or multi-media module 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, multi-media module receiver assembly or speakers.
