I finally got the NMEA custom output connected to my Trutrak vizion autopilot, formerly used by Avare and bluetooth Nmea with Android tablet.  Today I was using windows 10 on a RCA Cambria 10.1" 
  The Trutrak reported "GPS OK".  However once in the air I discovered there was no "activate flight plan" button or option.  But the proper course line appeared so I turned on the autopilot.
  I could not make the airplane follow the course line and it just seemed to cause the autopilot to wander all over the place.
  Unless someone can correct my use of I fly I will try it with a different laptop.  I also did not to remember if the heading data on the autopilot corresponded to the Ifly heading. Bruce Carlson
