Summary: nice big screen easier to see,love the split screen for lane assist , easy to operate. had a garmin 200w and thought this would be a nice upgrade the 200w has a 4.3 inch screen the 5 inch is much nicer. only used it twice so far. bought two one for my daughter the other for myself.
Summary: I think the 5" screen size is nice, though this is my first portable GPS system, so my main comparison will be with the built-in system in our other car (a Lexus), that screen is slightly bigger. I haven't used all of the many built in features but the basic functions work well. The map is very up to date as we live in a newly built up area and my parents live in an isolated area of a small town, coverage is excellent.
