Summary: As far as the features, screen display, size, quality...the Tom Tom is great. My big problem is with the piece that attaches it to my windshield. It doesn't stick well, and when trying to adjust it, it pops off or the Tom Tom pops off the attachment. I had borrowed my brother's Tom Tom prior to purchasing this one and it did the same thing.
Summary: Ok, here is the deal, I have been purchasing gps devices for many years, and have had some good ones, some bad ones, and some better than average ones. This gps is good but not great. The traffic feature that I purchased this for is not very good. Now I have used a garmin with the same feature and had the same mixed results, I live in a major metro area and this should be much better by now.
Summary: I had a TomTom 510 and love it but this 630 isn't that good. Took a trip to AZ. to visit my parants we got there about midnight and the 630 was 4 blocks off. The 510 was 1 house off, not to Happy.
