But my question is what makes it any better than an $89 GPS that has lifetime maps and traffic?
Campgrounds and rerouting around low bridges along a route really comes in handy. The along a route function which displays the distance to gas, food and rest areas really is nice.
Check your settings and make sure it's set for fastest time not shortest distance, and really get to know the unit and all of it's features and I think you'll like it. I did a cross country trip last year using one and I loved the information it gave me over what an $89 unit would give you.
