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.
Summary: I got this unit a couple of days ago. The unit did a firmware update then a free map update with no problems. The voice command works well and the 4.3" screen is a step up from my nuvi 260's. As of today no lockups, no power or shut off\down problems. Too date it has worked well. I have not used the media player, viewer, currency converter etc. and unless really desperate I will not.
Pros: Widescreen, voice command, garminlock, external antenna connection if needed. Free map update. Faster aquiring signal than my old nuvi 260. LANE ASSIST!!!
Cons: Nothing major. I'm not very pleased with the units custom power plug for the windshield mount but that is minor. The now standard mini-USB power would have been a better choice.
A few drawbacks, but love the voice recognition featur

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: The Nuvi 855 is very hackable, i updated it to the newest maps for 2011 no problem, just search google for the update instructions and save your self some hard earned money
Pros: The unit is very fast and responsive and keeps up with the navigation. system is pretty loud, not as loud as my stereo but it gets the job done. i like using the unit with the system auto dimming the screen, so it will give me instructions and upcoming turns with the screen bright and then dim and get out of the way while i drive or do other things. easy to add and change routes and gives you quick responses if you deviate from the original planned route. the intersec...
Cons: the unit HATES when you make it multitask. if i play music... crash. if i play a game.... crash. if i play an audio book.... crash. other than that, its great! if you get this GPS unit to... be a GPS unit, you wont have any issues!
Summary: i noticed alot of people talking about crashes, and bad battery life and not being able to turn it off. well... once you update it, it fixes multiple little bugs, just dont use the extra stuff on it if it crashes, its a GPS unit, not a iPhone ;) battery life has been EXCELLENT for me and the readings seem pretty close to right on. to turn off the unit, you have to make sure its not PLUGGED in or charging... etc.
Pros: this product is great! just make sure you upgrade to the new firmware. the battery has lasted quite long for me and the touch response of the software is fast and easy. the system comes out of standby very fast and its ready for navigation. comes with window mounting equipment, dash mounting and also a power supply for in the car and also a USB cord for computer charging and connectivity. the Lane Assist is very helpful! so great!
Cons: the system crashed when i tried to play music, audio books, or a game, although.... i havent tried it again after i updated the software. but i dont really care about those features, thats what the iPhone 4 is for :) software needs to be updated b/c of some bugs, so do that once you get the product.
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.
Feature Rich GPS - but it does freeze up occassionally

Summary: I've owned the Garmin Nuvi 855 for about a month now. I had an extra 12 volt outlet installed under the driver-side dashboard in my car so I could plug in and conceal the factory Garmin power cable that came with the unit. As a result, I use the GPS every day, every time I get in my car. That said, I find that the unit has all the features I need in a GPS and is much more comprehensive than my previous unit, the Nuvi 260W. PROS: 1.
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.
