A couple of words of caution about the GPS in new iPad, iPad mini, and iPhone.
First, none of them are WAAS GPS (nor ever have been, nor are any other phone and tablet that I know of), which means accuracy fluctuates, and this means you may not be exactly where you think you are, not very important driving a car on a road, but running channels through the flats or flying an airplane in the mountains when you can't see very well it can be very important. There are external WAAS GPS units that you can purchase and use with some Apps, but not all, and of course you'd now have two devices to power.
Second, something happened to the quality of GPS in the new iPad mini and I believe in the iPhone 11 (which probably also means in new iPads). My guess is the Chinese supplied a cheaper version of GPS chips than in previous devices without Apple's knowledge. I say this because when the new iPad mini came out I saw wild fluctuations in GPS accuracy, at times so poor that the GPS chip quit sending data. I worked with Apple on this for about three months. They confirmed my findings and haven't been able to fix it with software updates (at least not yet) which is why I say I think its a hardware issue. At the time the problem was restricted to the new Mini, but my new iPhone 11 Pro exhibited the same behavior a couple of times running on the water using Aqua Map, and I happened to be trying to get into a very narrow channel through the flats that I hadn't been on before. Took about 45 minutes for me to locate it the old fashioned way. This was before I got my Simrad with FMT/LMT which does have a WAAS GPS but per FMT's instructions I had to go into Simrad's settings to activate.
FYI, I've never had any GPS problems with any of Apple's earlier devices.
