Chase, I' be been following your discussion. I have the same problem my 492 doesn't "talk to my wheel
ST6002 smartpilot. I get SOG&COG but will not go to a way point. I have the same wiring
set up as you describe. Keep trying. I am wondering if the NEMA - from the 492 needs to skip the electric
ground and go to the AP? Also I have all the sentences on the Garmin
turned selected. Does any one know the correct ones to have on? Many be too much info going in?
Also I have a Matrix GX3000s I'm the system and it receives all info.
