how do you get around using navigation. that was the only reason that prevented me from turning off location permanently.

You know people got around fine without GPS (though paper maps are a hassle). I do use it if I'm in another city but that's rather infrequent.

Even in that case if I am driving around I use a non-networked Garmin. I apply updates to it before I go on a trip. If that fails I can always stop and ask directions. It's a fun way to meet people I never would have otherwise.
