1) I don't own a SatNav or a smartphone, never have.
2) Sometimes I rent a car, and it comes with a Magellan GPS system. Usually I just set a destination the opposite way from where I'm going, set the language to Portuguese or Mandarin, and let the woman yak.
3) Sometimes if someone is riding in a car with me, THEY will have a SatNav and ask me to program in a destination, which I will do for them.
So perhaps 1 out of ever 500 miles I drive in a car, there is a SatNav in it. They're hard to avoid. But met actually owning and using one? Not yet. I'm not that desperate yet.
