the product be good and easy to use . two flip side though : 1 . the garmin website do not work well with Firefox and it take I 1 week to figure that out and hence the map updation process be a pain in the butt . 2 . unless you put the antenna out of this garmin gp , the device do not recognize you current location and simply give you direction from the last current place , which be there when you use gp with antenna . so , it be not very obvious why be it happen and it take I some time to figure out what be go on . this problem be specific to all Garmin model with antenna , which suck . . ! 3 . other than that , device be just work fine .
