we old Garmin work fine but there be no free update . this model seem to have a wider screen and as a plus it have lifetime free map and traffic . can not figure out the traffic yet - it be probably a setting I have not find yet . something install with the word traffic in it during my first use so I be certain it be activate . Works similar to the old Garmin . I be not sure I like it 100 % , but it do more stuff that I need to get use to . the screen be definitely more responsive , as be change between menu . I have not try a location search yet . it be a little awkward with the mini-usb plug perpendicular to the back instead of attach to the holder like my old Garmin . when I take off the Garmin to walk or to put in glove box , I now have three separate piece to deal with : cord with traffic antenna , unit itself , and windshield mount . windshield mount seem sturdy . it be easier to take the unit out of the bracket than I think . overall I think this be a very good deal . if the traffic start work it may be a great deal !
