Garmin and other GPS systems can find places based on gps coordinates not just addresses. In situations like yours, that can be very helpfulBTW I don't have a smart phone or a mapping thing in my car, but I understand most are set up based on internet mapping services, and I tried looking up rural addresses and they won't always find it because the maps are differently inputed because here in Indiana it is county road 123 east box (or house number) 432 south and some will not understand it, i remember looking up something a few years back and having to type in county highway number 123 box 432. here we only have state and interstate highways.
