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 through this circuit. The
sound signal that has been sent is amplified by stereo component amplifier, and then is sent to 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, or speakers.
