Why are GPS units so much trouble.
I bought a Garmin Nuvi 5 or so years ago that worked most of the time,but occasionally went beserk.On our Christmas trip to South Carolina,it routed us one way going south and another way going north....

Any GPS is only as good as the map data fed into it. And that data may or may not contain complete and practical information. We volunteered at a Florida SP that had a county road run straight through it - on paper. It was a plotted road from years and years ago but now ends in a pasture field with several large wet/swap areas that the 'road' passed through. Use the GPS, but also check out 'paper' or online maps too.
