After having a smartphone, I wonder how these standalone GPS can survive. This is great to have if you don't have a smartphone and travel alot. Even though most smartphones' GPS system isn't in par with a standalone GPS, they get the jobs done when you just want to know the direction, and you get the best of both worlds. There are some advantages however, for example the screen size. Most standalone have larger screen sizes, and lots more functionalities. The battery for Nuvi 680 is great, and you can plug it to the car if low on batteries. You can't update the traffic over the air however, or I haven't figured out how to. You can also save favorites of frequent places, if you're that bad with directions. One thing that I notice though, is in cold weather, and we do get code weather here in Michigan, if I leave the GPS in the car for too long, it kind of freezes. Not to the point that it's not operational, but when turn it on it freezes for a second or two.
