Ive had my TomTom 510 for a few months now and hadnt really used it much until 3 weeks ago when I went to Illinois to visit my girlfriend. Let me tell you..it was a life saver. I couldnt imagine having to flip through papers trying to find directions while driving down the interstate. All you have to do is plug it in and let this handy little device tell you where to turn. The only thing I would recommend is buying an external antenna which cost around 20-30 bucks. If you dont have one its really easy for them to lose signal. btw..I love you baby!
