I've been following the comments with interest. I own several GPS units, Garmin included, and have a total of four GPS units in my Warrior (for various reasons).
I can say hands-down, the iFly 700 wins the prize. I've been so enamored with this unit that I actually removed the Garmin and re-worked the panel in my KR2 to accommodate the 700. There have been concerns and comments about the usability of the screen in direct sun, and those concerns and comments are valid. Walt has addressed the situation via the soon to be released iFly 720, which has a significantly improved screen for those of us that have unshaded canopies. There are a lot of features on the 700 that make it worth your attention. many of the capabilities clearly go beyond what we'd want or expect in a GPS, but they're handy! I have my checklist stored in the unit, a finger touch for each item as we go. This is just bells and whistles, but it sure is handy!!! The iFly isn't being marketed as an EFIS, so anything like this is a bonus. We're having a lot of fun with our unit!!! Via added memory and/or USB, we now have in-flight movies as well as a live external camera view. My unit is hardwired to the main power buss, off of the avionics breaker and switch. I have been able to make the unit freeze twice now, after diligent efforts to break it. In both of those instances, a simple toggle of the avionics master and the unit restored without a hitch. Often, avionics don't like RF. I've tried everything I could think of to "break" it via keying the COM radio, hitting test on the transponder, and even holding a handheld right against it and keying up. To my amazement, it just kept plugging along! I was going to buy a 2nd unit, and then the 720 beta came into view, so I'm on standby at the moment. I think what will ultimately happen is that the 700 will go into the Warrior, the 720 into the KR2. I'm absolutely sold on this unit. The performance is excellent, the customer support is superb.
