Dont know which to choose..different model different advantage...but for map view and fast refresh i will choose Nuvi 880 and Nuvi 255W instead Nuvi 50LM and Nuvi 2465,newest 2465 N 50 series doesnt show POI during navigations..but it's very easy to entering 1 sec traclog...so navigating using Nuvi 880/255W ...tracking a new track using 50LM/2465..n sometimes put both 255W and 2465 at my windscreen...sometime thinking should i buy all Garmin model to make the comparison...for now i think just enough,my wife will shout at me if i buy another 1 gps.
