Brian,
There is news. Several months ago (currently available) we released standard NMEA output specifically to support TruTrak interfacing in a way that a 396/496 would. So that means, our flight plan / DriectTo can be followed by the TT autopilot just like it can follow the x96 product using the NMEA output.
What we don't do is "full" integration where you can enable, disable and configure the autopilot from the EFIS. That is a lot more work and just isn't something Dynon can do in light of other features we are working hard to bring to our customers.
