what a world of difference have a gp device to guide we to unfamiliar destination on we recent trip . Tomtom be so accurate , we soon do not bother take the detailed road map and print direction along . we day of road trip with paper map be over ! Tomtom one be definitely worth the money . do not bother buy a $ 2000 + gp system integrate into you next car . Tomtom one will get you there for approximately $ 200 . a big bonus : you can use it in any of you car . Tomtom one be compact and fit easily in my pocket . a great buy !!!
