GPS is super-convenient when you're in an unfamiliar area. I sometimes catch myself thinking how did we ever get along without it. But we did. You just looked at a map before you set off, noted street names and turns, and paid attention. You would do the same thing and manage pretty well if you had to.
Of course it's convenient. But I learned to drive before we had it, and learned to find my way around without it. Maps helped, but you can do a lot with logic and by understanding direction.
