This is a Great GPS for a Great Price

I purchased this unit as a replacement for an older and larger GPS unit.  This Garmin Nuvi 40LM 4.3 is compact and very well made.  Being small, I'm able to rest the unit comfortably (vertically) inside my car's cup holder which eliminates the need for a separate holder or the supplied and ungainly windshield mount.  I don't recommend using the windshield mount because the suction cups eventually lose their ability to seal properly when mounted to the glass and can send your unit tumbling while driving.  Not Safe...The unit requires download of the free lifetime USA/Canada map when new and the download takes about 90 minutes to complete with a typical Internet connection.  Once installed, the unit operates very intuitively with the driver able to adjust the root as you go.  So, if you take a route that you prefer while driving, the unit responds by adapting it's directions to the change rather than arguing "route recalculation" as my old one did.  Voice prompts are loud enough to be heard even with windows down on the highway.  The display is bright and gives next turn distance and estimated time of arrival in addition the usual "moving car" icon and other information.  One of the best features is when the unit is run off the car's power outlet.  When you shut off the car, the unit automatically shuts down after 30 seconds and will then restart automatically when the car is restarted again and the map will pick up right where it left off.  No reprogramming is necessary.  This is a great value GPS.

This thing is awesome, so much better than my old GPS. The 3D maps are really nice, they make it a lot easier to translate the map to real life as you're looking around. The live traffic through your smart phone works great and will help you reroute around the traffic which is key because I, as I'm sure many others do, hate sitting in traffic. I haven't had to update maps yet because it's fairly new but I think the fact that I'll be able to get updated maps for life is a great idea by TomTom. My old gps was out of date and wanted me to pay something like $60 just to update the maps, which is crazy. I'm very happy with my go 60S.

It has all the basic features I need for a GPS. The price is great. It might make mistakes sometimes.

I love this GPS.  I use it all the time and it is amazing for saving me all the frustration of printing out directions ahead of time and getting lost.  It usually finds the satellites within seconds and only occasionally takes up to a minute.  Yes, it sometimes gives me directions that I personally don't think are the most convenient but I think it does as good as can be expected without it knowing which roads tend to have more traffic and stoplights.  In those cases I just keep driving towards the route that I want to take and it says "recalculating" and eventually will settle on my desired route.  The "go home" option is great when I'm out in a new place and don't want to meander all over trying to get home.  I like the projected arrival time on the screen but know that this is the time it will take if you're out when there is no traffic and if you hit the stoplights right.  But it constantly updates during your drive so that is nice.  Most importantly, this gps is so easy to use without having to read the directions which was one of the most important features for me.  I like the color scheme of garmin more than magellan or tom tom and I also like how the screen is black when it's dark out and cream-colored during the day.  The one-time new map download is great and after that it's something like $75 to download new maps but I think I can get by with updating maps every 3-5 years.  Overall great value and I use this nearly every week.  My mom had me order her the same gps because she likes it so much.  I have both the cup holder mount and dash bean bag because they are easy to pack away when I'm not using it so you don't encourage people to break into your car.

This is my first GPS unit, and I have had it for about 1 month, and used it on a few trips so far. It worked great right out of the box, just plugged it in and turned it on. The operation is generally intuitive, but where needed the manual is helpful. The screen is a good size and easy to see day, or night.

I bought this device after reading all the reviews from Amazon and I must say, I am not at all disappointed. This is an excellent product if you are looking for a GPS for close to $150. Has all the features which you don't usually get in any device in this price range. The TTS and Reality View features are too good and makes your life much easier...
The only glitch is that it takes some time for this device to lock the signal (not more than 3-4 minutes) but its something with which I can live with. I cannot comment upon the routing algorithm of this device but you'll find a lot of settings using which you can customize the route you wanna take for any place...

I would definitely recommend this product over a 100 times...!! :)

Can't attest to longevity as it is new...but this is a great GPS at this price point (got mine slightly cheaper elsewhere, sorry Amazon). The last Garmin I purchased was one of the original, bulky units that sat on the dash (sometimes) sand bag and all for over $500.00. Gone are those days and here is a unit with a great display, suction cup, and features as well as lifetime maps. A good package all around from the leader in GPS. I've been through a Tom Tom (user friendly, but lacked features) and even a Magellan. Full circle, the new Garmin Nuvi 55LM is a slim, sleek, user friendly unit with features such as trip planner, logging your trips, and even option to use as a rear view camera with additional accessories. The 5" display is more than adequate; 6" may even be cumbersome. Some would say.

I really like this GPS.  It is very easy to use and the touch screen feature is really nice.  The screen is a nice size and the graphics are easy to see.

As with all GPS systems, the route the computer selects isn't always the best.  And you do have to pay extra to load the most recent maps.

The Garmin is the best GPS there is and this one was an awesome price.  I think the lifetime maps for the US is also a wonderful add-on.  I already own one of these myself and I bought this one for my husband who claims he never gets lost but always wants to borrow my GPS when he goes on a trip to our son's college in upstate NY.

This is a great, reliable GPS that does everything I need. Amazon generally has a really great price on these. If you are interested in an entry level GPS, you should seriously consider this one compared to the others. Garmin's feature set and routing capabilities are almost always better than the other brands.

This is a great buy for a complex three way GPS that is good for trails, the road and also for marine.  It has fully loaded maps and operates like a dream however if you are in an area of new developement, it doesn't have the latest roads and Freeway exits.  In my case it causes quite a bit of problem because I live near a new exit that was opened about 18 months ago however when my trip takes me to the Freeway it will route me to the one north or south of me and will keep telling me to make a U-Turn when I go the correct way.  The past two years have cause our area to expand so rapidly that when I drive to a place an then locate myself on the GPS it will show me sitting out in a field.  A new map will cost about $75,00,

This was my first GPS unit.  For years I have balked about getting GPS, thinking why do I need it when I have Google maps on my phone?  Then I went on a trip with someone who had it, and immediately saw the difference.  There is no comparison.  This model is a great value for the price.  Plus it is really easy to use.  Very intuitive.  It did not come with a manual, but you really don't need one.  And you can download one from the Garmin website anyway.  Used it last week for a vacation trip all over The Berkshires and it worked like a charm.

As for Amazon, I received it the day before the expected delivery date.  That's always a happy surprise.

Very happy with this purchase.

This was my first GPS so clearly I did not want to spend a lot on it.

This completely works for me.  I love the clear lane designations, especially when you are in cities to which you have never visited.

I did have to make adjustments after reading reviews, such as I cleared out all of the other language and voice choices before I tried to sync it on-line.

It was pretty easy to use outside of the box.

It is not that great to use in rural areas but that may be the case for all GPSes.

I have been using this GPS for a few weeks now.  I have not found any issues where the maps were incorrect.  For the price I paid, it was not much more expensive than 3 or 4 years of paper maps.  My only complaint is that it seems like you need a zip code in order to find an address and I don't always know  what that is.  That being said, there is probably a way around that that I have just not figured out yet.  Great basic GPS with a nice size screen.

The feature you get for the price are great. I'm on the road a lot and a GPS is a must.
I love the traffic update.
The accuracy is better than my old GPS.
The touch screen is a little unresponsive at times. Seems you have to press an item several time to register.
Garmin is the only brand of GPS I've ever owned. It's the only brand I ever plan on owning.

I bought this GPS after having a very expensive one that was stock in a leased car I just returned. I am very satisfied with this GPS. It far exceeds my expectations. It is very user friendly, easy to set up and its accuracy far exceeded my expectations.  I recommend this item to all my friends.  I HIGHLY RECOMMEND THIS ITEM!!!!

The c520 is an excellent GPS at a great value price.

The unit does take time to get used to since the user interface is not the easiest. If you are a geek like myself then you will have no problems using it, but if you cannot program your DVR then this unit is not for you.

The unit occasionally crashes with a Windows fatal error message and reboots back. This has not been a problem for me since its only happened when I am playing around with the options while navigating.
