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....

The Zumo doesn't make many mistakes and both my units have lifetime maps which I update frequently... In most instances, you get what you pay for.....
This is a very accurate description of the use of ANY GPS system.
"It doesn't make many mistakes...." and "In most instances....."
A GPS is a tool. It's not magic! Follow the information but do not follow the information blindly unless you don't mind ending up in a dead-end street. This would not be a concern for me if I was driving my towed but it would be a huge issue if I was driving my RV while towing. :S
