Guys, I used a program called GPS Tracks on my iPhone.
It's a freebie that isn't a road GPS at all, but a Garmin-type GPS that we had for hunting and stuff way back when. It's for marking waypoints and keeping track of where you are and where you've been, but just uses latitude and longitude to mark those points.
It works on the water, in the air, out in the woods, on roads, or any combination of those things.
It's Free, I do believe. I got it when I needed to point my HD antenna. It works great.
