Doc,
I just picked one up for my wife, and like you, it was our first car gps. I have hand helds that I use for hiking/hunting/fishing, ect.
It has a nice and easy Graphic User Interface (GUI) with a touch screen. I was able to figure it out without reading the directions, which is nice to use while driving. I'd hate to have to pull the directions out while driving while juggling the gps around...
Any how, the software IS NOT upgradeable which is a bummer. And it gets flakey in the city. We used it in NYC, and in Philly, PA, and it would lose its signal around tall buildings. NOT GOOD!!
We are not in cities much, but when we are, we want it to work. Just something to think about. Personally Id go for an upgradeable model, with good city reception. But it is a nice unit otherwise. I wish someone had told me this beforehand. Hope this helps,
