I have nuvi 205W - well I don't need fancy features but good road navigation
and garmin sucks in that matter. Too many times its road selections are simply stupid, illogical and make no sense whatsoever. e.g I was driving once the highway and I knew my target was just off that road many miles ahead and it all of the sudden told me to exit, make big detour and come back to same highway...fortunately I didn't listen to garmin idiotic suggestions...
I could write more about very bad garmin navigation program but no time for it.
