In communicating with Shane at Advernture Pilot today, it appears that the problem lies in my default boot-up screen coming up in GPS. Shane suggested booting up in the main screen and then click on GPS. Although I have not tested it with the Autopilot (and the Dynon D10-A), I have tested it over 15 times and in every case, the NMEA Output Controller is recognized. I have very high hopes of having this licked at this time. Will test on the Dynon over the next few days.....
