As an update, I bought the Nuvi 200W...
So far, I've had it about a week. The unit itself is flawless... locks onto satellites in under 20 seconds, places you on the map where you're supposed to be. It also has a very large screen, as compared to some of the other Garmins.
I have found two instances where the base map is incorrect... one place it tells me to turn left, and there is a jug-handle with no left turn; and the other is my parents address doesn't exist (very rural area). So you, as the user, still need to have half a braincell to drive. This has the most updated Garmin mapping software, so the rest of you have the same stuff.
However, so far, the roads exist. I like the fact that if you aren't navigating somewhere, it simply tells you (via a text band at the top of the screen) what intersection you're approaching... I find that very handy! It doesn't do text-to-speech, but it gives enough warning that it isn't needed... the voice sort of annoys me anyway.
It has a lot of points of interest (over six million IIRC). If you aren't looking for a POI in close to you, it does take several minutes to search its database (say you search national park, it might take 5 minutes to list ALL the locations with "national park" in the name. The unit has almost 1 GB of "stuff" stored in it... I have found a bunch of stuff near me that I never knew existed...
Although it is a very basic unit, it is exactly what I wanted. The wife likes it, as it shows intersections and names before we get there... so it will help her navigation by maps (she finds places the look interesting, then tells me which way to go).
Overall, we are very pleased with it... I would highly recommend this as an intro-level GPS.
