NAVIGATION / MULTI INFO DISPLAY  NAVIGATION SYSTEM(for Gasoline Model with RST Switch)  Microphone Circuit between Microphone and Navigation Receiver Assembly  


DESCRIPTION

The navigation receiver assembly, map light assembly (telephone microphone assembly) are connected to each other using the microphone connection detection signal lines.

Using this circuit, the telematics transceiver sends power to the map light assembly (telephone microphone assembly), and the map light assembly (telephone microphone assembly) sends microphone signals to the navigation receiver assembly via the telematics transceiver.
