Sound Signal Circuit Between Radio and Navigation Assembly and Stereo Jack Adapter

NAVIGATION: NAVIGATION SYSTEM: Sound Signal Circuit between Radio and Navigation Assembly and Stereo Jack Adapter

Sound Signal Circuit between Radio and Navigation Assembly and Stereo Jack Adapter

DESCRIPTION

The stereo jack adapter sends an external device sound signal to the radio and navigation assembly through this circuit.
The sound signal that has been sent is amplified by the stereo component amplifier 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 radio and navigation assembly or speakers.
