Navigation schematic - wiring diagram - where microphone plugs in?

Would anyone happen to have a wiring diagram or schematic of the Navigation components?

I have a MS6 and am trying to understand where the CX-7's microphone 'plugs' in...i.e. where the navi's brain is as well. And..where the 'talk' button plugs in as well.

If anyone has any information, or insight, Much appreciated!
