GO 4 TomTom 510 to you
I do a lot of traveling and purchased my first 510 last year. My wife, who is directionally challenged, marveled at how easy it was for me to find any destination without even looking at a map. As a result, I purchased her the same model for Christmas. She says this is the best present I ever gave her! It was easy to use right out of the box, and generally right on the money. My only complaint is that it sometimes takes a few minutes to catch the satellite signal.
