Drawing E shows GPS/XTE data going from the BT adapter to the baudrate converter - however the line from the GX2150 to the BT adapter contains only AIS/DSC data not GPS/XTE data - so you are missing something there.
Looking at my GX2100, I don't see the required sentences being output for the autopilot either. Reviews of the 2150 did not mention that this was added. Are you sure they are there?
