I've used it for the first time today, on my Lumia 920. I must say, at least in my area, it is very accurate. No rerouting messages, when you don't go the exact way it tells you. It just tells you where to go, when you do. Example, I went straight, instead of making a left, and it just told me to make a u-turn, when I got to the next intersection. It also works through bluetooth, the speed limit settings work pretty good.
This navigation app should be a joy to use for most people. I plan on testing it further, when I get a chance. But, for now, I think it's one of the better navigation apps out there, I would dare say right up there with Google Drive. Actually, I do dare to say.
