Paper Maps are on the rebound.
Re: Andy's point.
Just carry an unfolded paper map in your lap. The legal system is a mess. I watched a Youtube video a while back, concerning talking to the police and what it can do for you ... NOTHING!
The US (all states and the federal government) have so many laws the you are most likely violating one if you simply breath long enough.
Oh well ... this will never change.
