What is the exact advantage of having a display device that can be get GPS? Do I understand that it's because then the Maps off Google (or wherever) will update as you fly? Do the Maps really change that much that you need instant updates? I could use my iPhone 7, which has GPS, Or my iPad mini2, which is just Wi-Fi, and outside, obviously, doesn't connect to any network. So what's the answer here?
What does my iPhone do with GPS that my iPad does not do when I fly?
