Don't get me started on those things. My first experience was when we went to my eldest son's graduation from Air Force Basic Training. The hotel we were supposed to stay at, the GPS told us the offramp before the one were supposed to exit. After a few turnings-around, the wife finally called the hotel...which was one offramp
further. I'm especially appreciative of the part where the stupid thing tells you, "Turn left in 40 feet" when you're driving at any kind of speed...not. I have a friend who has used the GPS in some travel finder, and would have ended up driving down a
steep embankment or into a cornfield. He's a smart cookie- he didn't do those things!
