any one is better than no one. I am still using Tomtom one. It works fine. I tried newer one.I even tried on one PDA. None of them are 100 percent. But they all lead you to the distination one way or another. I found the more information you get, more distracted you are. Buy a simplest and cheapest major brand. tomtom , garmin Magellan. Leave it in the car, you don't need to worry it to be stolen.
