Summary: I've had the Nuvi 850 for a couple years and could not be more pleased with it's performance. Contrary to another person's review, my 850 has never once taken me to the wrong place. But, you have to know how to set the preferences. You can set preferences to: Fastest route or Shortest route. If you have it set for Shortest route, it will take the back roads. Also, you need to look at the route it wants to take you on and decide if that's what you want to do.
Overall, I love this GPS and just bought a second 850 for my jeep.

Summary: I drive a wrecker for a living and pick up 10-12 cars a day, My old faithful Garmin C550 was starting to act up, the touch screen was getting hard to operate and it would have mystery shut downs (over 100k miles logged on the trip meter), so I replaced it with the Nuvi 850. I have logged 28K miles on the trip meter and couldn't be happier with it.
Summary: My first Garmin served me very well but I was intrigued by the voice recognition feature of the 850. After almost two years of use, I would not be without it.. Nicknamed "Trixie" she never lets us down and saves all the anxiety associated with being Directionally Challenged. For first appointments, Mapquest gives me the time it will take to make the trip and leave the house 15 minutes prior to the appointment time. I have not been late since! A wonderful investment...
Summary: I am so thrilled I bought the Garmin Nuvi 850. It is hands free with the voice recognition feature. I did have to go online for the user manual to figure out how to set the voice recognition up. It is not in the quick start set up guide provided. I would recommend this product to anyone. Awesome!
