I loved my 740, but for my panel display it was too small. For the last almost 3 years I have been using a 12.5" IPad. At the time i bought it, it was the only way I could use my Stratus and use Foreflight - I had to buy Forflight (which I loathe) for a year in order to be able to access Canadian charts for a trip to Alaska. Now, back exclusively on IFly. Although the 12.5" IPad is better than nothing, in any kind of bright light it is only BARELY better than nothing. And it is an IPad with all the cranky, obtuse features to torture users that only Apple can devise. And at well over $1k its not cheap either. Although I would gladly pay twice that or more for an 12" version of an IFly 740 super bright.
I wish that IFly woud build a large format version of the Ifly740 with a high visibility screen. That would be the utlimate answer as there are so many great things about the basic 740 that I like such as the ability to (wire) output NMEA GPS nav data into my Dynon HSI (and music into my audio panel).
Or lacking the ability to produce a 12 inch Ifly, find an Android device in the same size range that has superior viewing in bright light. So far I have had no luck with that.
Also if neither of the above were possible it would be great to have an interface device so that IFLy on my IPad had these 2 features:
The ability to use a trackball as the interface, to avoid playing touch scream when trying to work a panel mounted touch screen in turbulence.
The ability to output wired NMEA output from IFly running on an Ipad so that I can connect it into my Dynon. I could again then let the output from the IFly go into my HSI on the Dynon and use it for direct nav & Autopilot input.
