I have seen commercial gear, about to be offered at about $1500/car
which gives the scrolling map with the next few street names shown
and the route to your destination highlighted.  Said to save about
10% for delivery vehicles in both time and gas.  Thus pays for the
system in a year or so.  The interesting point was that they had to
develop their own maps.  No existing available maps were sufficient
in accuracy for the system.  When installed, the self contained
where-am-I system uses wheel sensors most of the time, but corrects
by assuming that you mostly drive on the road and turn at corners.
It stores its map on (cheap) mag tape, which is fast enough.

Amazing, commercial, inexpensive, and with lo-tech data storage.
