I have a lot of Paid map apps on my phone, but in the end, none of them can match the latest version of Google Navigation for turn-by-turn. I hit the microphone and say "Take me home" when I am confused as to how best to do that.
Or, as mentioned, "Navigate to 123 anywhere street, San Diego, California" and let it run.
CoPilot USA is a great map app for sitting at the lunch counter and trying to figure out where to go, and what to see. But it is a PITA on the road, because once you make that "right turn" it does not verify that you are now on the correct road. It is just as dead as a log until it is time to turn again.
I quit using it, it is only a research tool now.
