I did a lot of research before buying this. Was looking for the features this one has, including the ability to update maps, and was not too pricey. There are better units, but you pay for that. This works well for me and my family. My wife especially, who is directionally challenged, uses this GPS around where we live and it has saved her tons of times. Used it last summer for a trip to Florida, big, big help in getting around somewhere I had no idea I was. Did run into a couple of glitch spots which other reviewers mentioned-places where directions/road don't match up with GPS, but few and far between and usually within a mile of the 'glitch' spot, the GPS was able to relocate our position accurately. Believe, it is much easier find your way using this GPS than taking directions from passer-bys when you don't know where you are.
