I order this device after Consumer Reports rate it a best buy , favor it above other more expensive model and I be not disappoint . this way exceed my expectation , and the thumb wheel -lrb- instead of the touch screen -rrb- be great , work similar to a blackberry . the voice instruction be clear and straight forward . I would strongly recommend that you also purchase the three-sided Garmin friction base so it sit on you dashboard . for the extra $ 30 , it work well . I have only have my Garmin a month or so and already , three friend have buy one just like it after see mine in action .
