I bought this for my dad as a Christmas present, and it worked great right out of the box. The only thing I thought was a little strange was that it came with no manual. There is a Quickstart guide included, but if you want a manual, you have to download it from the internet. We took it on a test drive to a location that my dad knew well, and he took a shortcut that was different from the way the Nuvi directed us, it immediately recalculated, and took us the rest of the way on the route that my dad was planning to use. The voice directions it gives you are easily understood, and given well in advance of the turn.
