I have be use this gp around the Boston area for about a month , and I think it deserve a solid 4 star , but some quirk keep it from earn 5 star . I be debate between this and the 3790 -lrb- which ultimately prove prohibitively expensive -rrb- . I be very happy with the large size of the 2460 - the 3790 be nice and slim and pedestrian-style portable but I have only use my gp in pedestrian mode once . have a bigger device in my hand do not cause a problem for the short amount of time I be use it . the eco-score feature have actually get I to drive more efficiently -lrb- i.e. more slowly -rrb- on the highway and I have experience a real increase in my mpg rating -lrb- I use to score about 26mpg , now I be up around 30 -rrb- . I love the `` at the pump '' feature , which track you mpg rating when you put in mileage and fuel stats . the ability to customize the home screen be great , too . I have add link button for `` where be I '' and `` at the pump . '' Bluetooth work great and I be thrill to be able to use the voice command to access my address book . speak of voice command , it be a great feature that I be happy to have . I would say it be about 85 % accurate . it can not hear you if you have get the radio on -lrb- big deal , just turn it down for 5 seconds -rrb- and I feel much safer use vocal command to find my destination than lean over the dash to type they in while drive . unfortunately , the Garmin keep disappointing I with the way it route I around heavy traffic . most of my driving be on the highway in suburbia and the traffic datum be supposedly pull in over a FM link and in my case be only accurate\/updated if you be within a certain -lrb- close -rrb- distance of the city of Boston , so usually I find out too late that heavy traffic be ahead . it also often suggest I get off the highway and back on a mile down the road , which never work out in my favor . I be think I will shut off the traffic avoidance feature altogether . in the Garmin 's defense , when you be in traffic in the Boston area , there be no way to avoid it in any meaningful way regardless of what gp you have . a few time I have tell it to take I home through local road , and I have enjoy the slow and easy scenic drive and have not worry about get lose , but they have not really save I any time during my commute . all in all , I be very happy to have get this device , especially since I get it on sale for $ 200 . I feel good know I have lifetime map and love the voice command feature and the large size . traffic datum have be a letdown but that be my only major complaint .
