Summary: The 855 has a big advantage and big disadvantage. Big Advantage: Voice activation. Commands can be spoken instead of being entered on the touch screen, so it is not necessary to stop. For a RVer pulling a travel trailer, this feature is very useful when approaching a freeway on-ramp and not knowing whether to use the right or left lane.
A few drawbacks, but love the voice recognition featur
21 November 2010
Summary: This is my second nuvi 855 as the first was recently stolen "atleast they did not think to grab the steering mount remote to activate the voice recognition feature" It has a good many features that I never utilize, but with a job that requires I need to find 5 to 7 addresses a day, it works great. I love the voice recognition which keeps my eyes on the road though it has problems with background noise. No problem with quieter vehicles.
Summary: After downloading free updates (one time) from 'Garmin', the GPS functions great. Just lovely. Lane Assistant is seamless. You see every intersection, all lanes ahead, and it tells which lane to choose ahead. With my hoarse voice, I was scared it wouldn't accept my VOICE COMMANDS. I tell it to 'go home', and it obliges "respectfully". The 4.3 inches size is a plus. So far, I'm loving it.
Summary: I bought this GPS knowing that Garmin is a good brand regarding GPS-s. I didn't expected to get the satellite signal so fast, the way that you find you way around with it and how easy the menu is. In my travels I notice something that I , personally consider that is a bad thing, the time is missing when you driving and you looking at the map, you either have to type to see it or probably talk, I didn't try to see if is working with voice command.
Summary: Coming from a built-in nav user (LandRover) there are some things that I like better on the Garmin, and of course some things that were lacking. Garmin (vs the other two top brands) has a feature I really like...you don't have to know the city of the address, it'll pull up all the street name & #s results, then you can choose from there.
Summary: The 855 works as you might expect. Maps on mine are not up to date. I ran through the update but they still are not current with my area. The internal speaker volume is a little soft and the FM xmtr needs to be very close to the local radio antenna. All in all I do like the product and plan to use it on a regular basis. Note: I also have a Magellan. They are about equal.
