a big feature for this unit be the lifetime traffic and map . more and more manufacturer be do this and it be great for we the consumer . make life a lot easier and we will hook the unit up to the computer to get the map . while do that we will update the software too , which might not happen as often otherwise . I have use various tomtom before as well as many other gp unit . this unit have a great screen . big and easy to see . unless you be get sun on it . screen get wash out in sunlight . the menu be fairly easy to use and maneuver , but can get confuse at time try to figure out where to go . IQ route be great . nice to have that in calculate route . but cancel a route be too complicate . Satellite lock be quick and solid . Lane guidance and exit sign be great . in fact TomTom seem to have more of they than other unit I have use . I like the flash green arrow to show you what lane you should be in . nice , visual feature . big complaint I have be the mount . it be way too hard to attach to the windshield and the GPS have fall off more than once . give I the traditional mount please ... these ez mount be anything but ez . not a bad gp with some nice feature . but ultimately , I need to be assure the unit will stay put and be able to see it in the sun .
