I’d like to here your impressions about the Garmin vs Dynon, and why you chose Garmin.
A lot went into the decision. At the time of my build, finances were tight, but I definitely wanted a glass panel. Garmin had just come out with the G3X (non-touch) portrait style displays. I wanted landscape displays, and the price point for Garmin was just slightly out of my reach. I was happy about Dynon's early ADS-B solutions, their autopilot, and AOA. I flew with (and added to) the Dynon system for 5+ years and nearly 450 hours. It's a great system.
The decision to switch to all Garmin ultimately came from the installation of the GTN-650 and my desire to start flying IFR on a regular basis. I trained for and took my instrument check ride in my RV using the GTN-650 and Dynon Skyview combination. The integration between the two was really good, but not great...not perfect. Simple things like how the flight plan and approaches were graphically displayed on the Skyview and the Dynon autopilot performance during approaches, was not up to my liking. Again, it was good, but not great.
I went to Oshkosh last fall and played with the G3X displays for hours, spoke with the great guys at SteinAir, and decided to make the switch. The integration between the G3X and GTN-650 is seamless. Also, adding the GTX-45R transponder gave me full functionality out of the GTN (secondary traffic display, ADS-B In, etc). The Garmin autopilot works great right out of the box with default settings. The GTN flight plans, approaches, holds, leg sequencing, etc all display perfectly on the G3X.
After I came to terms with the financial investment, I'm very happy with my decision to switch to Garmin. I would not hesitate to recommend the Dynon system though...it's a really good system. Both systems are top notch, but for me, it came down to how the system integrates with my IFR navigator. My complete Skyview system will be put up for sale here on VAF as soon as I can organize things and figure out a fair price.
