I pick up one of the Tomtom Ease GPS unit , when Woot ! have they for $ 29.99 . I figure before this , that my handheld GPS unit or my wife 's smartphone would work just as well , and in some way , they do . however , on we recent vacation to Oahu , I take the ease along and use it in the rental car . I do not think I will ever travel to a different city without it now . be able to enter a address , and have clear , easy-to-follow direction on how to get there , sure beat the heck out of try to figure out a good route from a paper map , and especially beat the heck out of try to remember the route from the paper map while drive . if we decide to detour -lrb- or , if because of traffic congestion in downtown , I could not change lane to make the next turn -rrb- , the unit automatically calculate a amend route , and in most case , give a pretty good ETA base on its programming of the route and we current driving condition . my wife 's smartphone sometimes have problem figure out where we be , or how to get where we want to go , but so long as we be not inside a tunnel or a parking structure , the ease lock onto the gp signal fairly quickly , and then calculate the best route . about the only time I have a problem enter a address , be when I inadvertantly select the wrong city -lrb- there be two city of the same name , only in different county . at first , I choose the wrong one -rrb- . it have a decent database of point of interest , and a surprisingly comprehensive list of street and location , right out of the box . the only time its direction be a problem , be when I be go to the Pacific Aviation Museum on Ford Island . the ease give I direction right to the museum , which would have be fine if I have military base access privilege . have I select direction to the Visitor 's Center , from which a shuttle bus take civilian visitor to the museum and other Ford Island site , I have no doubt it would have give I correct direction . this be a case of , `` oh , shoot ! it do just what I tell it to ! '' the ease do not have some of the extra feature that would have gain it five star from I . if you be look for a basic gp navigation system for you car , and do not have bucketload of money to spend on one , this be you answer .
