I am a huge fan of copilot. great gps, I'll never buy a hardware gps again.
Cost is pretty damned cheap, especially compared to that $400 plus rand McNally, Magellan, or garmin.
The paid gets you turn by turn directions, without it you just have a map.
Still cheap, still worth it.
Imagine my surprise last week when I got a new Motorola droid turbo, and google play said my device was not supported. I contacted copilot support, same answer, perhaps in a future version, timetable unknown.
At least it still runs on my transformer tablet.
