I don't know if they can be tuned from an ipad. I have a 3x5 card that I print out. Each line lists the airport, radio freq's, pattern altitude, and traffic pattern. I fill one out before I fly. I carry an ipad with foreflight but i tend to enjoy the manual tuning from my 3 x 5. I don't even have my local airports programmed into the memory. I had the V10 in my first plane but I like the knobs on the V6 much better. On my kitfox build, I am using two mini efis panels. I also use MGL transponders in both planes.
