The TomTom 140s is a full featured affordable car navigation solution. At the time i bought it it featured one of TomToms exclusive technologies which shows you the lanes you must be in for merging or exiting highways. Although this may not seem too impressive, it really helps when your driving on a crowded highway, somewhere you have never been. Another TomTom exclusive (that I know of) is its integrated suction cup. The mounting unit clips on to the back of the device and can fold down resulting in a compact package when not mounted. This makes it easy to remove when your not in the car and fit in your glove box or even purse/pocket. Everyone knows that even the suction cup should be removed from your windshield so thieves don't know/think there may be a GPS in your glove box. Also, from my research, the 140S is the most affordable TomTom device that supports spoken street names. All in all i am very satisfied with this unit, only once did I end up in a sketchy side of town trying to find a Burger KIng.
