For what my fellow drivers and I need, the old nuvi200w is
just great. I can get good deals on them on e-bay. As far as the
upgrades are concerned, some used ones were either never registered with Garmin, or the single free map up-grade was never used. When you go to their web-site, and register your self, with Username and Password, then go to where it says to register your unit. Of the last
four I've acquired, two had a free update coming and they and one other
were never registered, so I put them in my name and registered them and got the two free updates by download. The fourth was registered, but had a recent update. You used to have to spend $10 bucks for the first update by DVD in the mail, or spend 2-1/2 hours on a 1.4 G-byte
download. Way faster now. The website reads the info on your GPS, and tells you what you need. Hope that helps, TACC1.
