I'm just saying it's more difficult with a 3"x3" screen that covers maybe 1 square mile, then it is with a 2' x 3' piece of paper that covers a few hundred square miles, because positional indicators may be visible that are further away then the tiny GPS map will indicate. Yes some GPS units may be able to zoom out, but honestly this is 50+ and trying to read a map that is marked in a 2 point font is going to be an exercise is futility for most of us, even with our glasses. In cities the GPS maps seem to be pretty good, in rural areas they tend not to be, especially here on the Bruce, where I have seen people with GPS driving through empty space, because the county road they are on, isn't in the right spot on the map, it's way off to the side, even though your on it.
