Summary: I bought a voice command Garmin thinking it would beat typing on the touch screen. I returned it because this feature was not useful to me. What its good at is finding common places, like McDonalds, Safeway, Costco, or Walmart. It finds you a close one and does it well. What its bad at is finding an address. Instead of searching nearby, it looks at every street in the USA and finds a match, which rarely is the right one.
Summary: I brought this for my trip to Europe this June (northern Spain and southern France). What a disaster! The device just went blank on A64 on our way to Eugenie les Bains (I am glad it did not quit while we were driving in the Pyrenees). We ended up using my AT&T iPhone to guide us there. I looked up the manual (on my iPAD) trying to figure how to re-start.
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.
Summary: Of course you have to turn off the radio (duh?). I have had a 850 for a few years and find it very useful. I've had no problems with mine except the battery went south but that happens. But then I don't have unreasonable demands on products.
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: When you choose a Garmin, you have chosen the best GPS. You can always rely on the fact that it will get you to your destination quickly and safely. The device is intuitive, however if you need to refer to the manual is well written.
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...
