I do not know if it be only mine , but in about 10 % trip it lose the way , one of the obvious mistake happen near my house . the real distance be less than a mile straigh but GPS make I turn and it take I around by small one-way street for 30 min till I give up . and what be worse my husband trust it to take he to Newark airport and it take more than 2 hour -lrb- instead of 1 hour -rrb- and he almost miss he plane . I do not know if I can return it and try maybe TomTom GPS . I have 2 friend with Garmin that also lose they way from time to time . I do not find any other problem with the device , I think interface be easy and unless it lose way totally - it be perfect in make d-tours and finding place . though it be own database be very poor , for example it can not find TARGET store in White Plains , NY that be open 5 year ago , therefore one have to find the exact address and go by it . in my experience it also could not find Staples , Bestbuy in Scarsdale and Wal-Mart . I do not even try to locate small store . well ... anyway it be better than nothing and in case of emergency maybe a lifesaver .
