I live between Boston and Worcester and the NAV has worked great in both places. I've lived in Mass for 14 years, so I probably could have lived without it, but once or twice a month I use it to get somewhere I haven't been before. Looking at new houses now so it's a benefit there.
I would say if you are not from around here, definately get the NAV. Not only are the roads screwed up, so are most of the drivers!
