I have a 720 iFly GPS in my RV-6A. The company is relative new and still has some bugs that are being resolved with software updates. Yes, i have had some problems since buying it at sun n fun 2011. The company has been extremely responsive to my problems. I expect a software update within the next few days that will hopefully solve a new problem and provide some new interesting features. I really like the maps and the other many features. The 720 upgrade from the 700 incorporated a brighter screen for day time use. I made a quick removal, swival attachment to my panel. It also has a great street GPS capability that we use on our road trips. The unit is wireless and easy to get online for updates of maps, TFRs, etc. I have it talking to my Trio autopilot that works just great. For the money, I consider it a great deal.
