I'm kicking around avionics upgrades for a Grumman AA5 and right now I'm bouncing back and forth between a full Garmin suite (G3x, GNX 375, G5, GFC 500) or the Dynon Skyview HDX suite with a G5 replacing the D10, a GPS 175 as the IFR navigator, and the GFC 500 (going this route because the Dynon autopilot is likely not getting certified for my aircraft for the foreseeable future). I'm curious to hear from anyone who's installed the Dynon + Garmin Navigator and potentially anyone who's installed the two with the GFC 500 Autopilot. How is the integration between the two sides of the panel? What information can get passed through the ARINC-429. From what I understand you can't modify flight plans from the HDX and send them back to the IFR GPS correct? How tedious is this? What are the pain-points? I'm currently leaning towards the Dynon/Garmin combination due to the cost, understanding that I might lose some things in terms of full integration.
