Sound Signal Circuit Between Navigation Receiver Assembly and Stereo Jack Adapter

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

DESCRIPTION

The stereo jack adapter sends an external device sound signal to the navigation receiver 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, navigation receiver assembly, or speakers.
