Good little unit for the money. The MSN feature is nice when you are in areas that it supports. I'd love to see them add a doppler radar page to the MSN service to really raise the bar. I don't like the MSN hardware portion being built in to the cigarette lighter adapter but it is what it is for now. The price was right when I bought it and it has been worth the amount spent without a doubt. My father has borrowed the unit and enjoyed it as well and he is not tech-savvy. The roads are pretty up to date in my area, rerouting is pretty quick and intuitive as well.
