NAVIGATION / MULTI INFO DISPLAY NAVIGATION SYSTEM Microphone Circuit

DESCRIPTION

The navigation receiver assembly, map light assembly, microphone assembly LH and microphone assembly RH are connected to each other using the microphone connection detection signal lines.

Using this circuit, the navigation receiver assembly sends power to the map light assembly, microphone assembly LH and microphone assembly RH, and the map light assembly, microphone assembly LH and microphone assembly RH as sends microphone signals to the navigation receiver assembly.
