I bought this for my husband for father's day and decided to give it to him early as we were headed to Boston for Memorial Day weekend. We rented a car and were off in the city and all surrounding areas without so much as a hitch. This is a lifesaver for anyone traveling in new areas. Helps to make you a more adventurous traveler.

this 670 had a deffective battery, which was discovered the second time we used it. No support over the weekend, so 4 days of the trip required maps only, purchased at a filling station, WORTHLESS. Then a 2 hour hold and 30 minutes with the tech to get a Return Authorization. I must pay to return a new DOA $500 GPS, and await a repair or replacement. Secondly I purchased this unit because of the pre-loaded European Maps, HOWEVER the loaded maps are outdated but new ones will be sent to me AT NO CHARGE in 4 to 6 weeks. Third the window mount is pitiful, will not hold and the unit constantly fall off, luckily into my wife's hands. One day it will hit something and then the screen will break and that is the end. Fourth cannot change destination while using. You must exit GPS add address and then re-boot. Krazy and very bad!!!Garmin must be just too good at selling, because there is absolutely no company in today's fast paced World that will survive with this lack of speedy resolution to a NEW & DOA product failure. Garmin charges for everything. The city guides installed are minimal and you must purchase detailed ones AT ADDITIONAL COST. The GPS chip costs about $1 the 670 had 2 GB of internal memory $5 so what are the outdated maps and minimal city guides really worth. I have used a co-pilot with mu Sony laptop for years great European maps detailed city etc. Garmin is now my very expensive and worthless dash decoration.

The Garmin nuvi 670 is the first GPS I've owned, I've used them in rental cars, but decided that since I travel so much, I needed to own one. I bought the 670 rather than the 660 although no trip to Europe is planned right now; the cost difference between the 660 and 670 was about $100, and Europe maps cost about $200.

The unit is great so far. Mapping works, although it doesn't know some recent roads. I travel alot, both in the city and in very rural (gravel road) areas. The routing in rural areas was weird - took me miles out of the way, but later I learned that the "avoid unpaved roads" was turned on. I've unchecked this option and will try again soon. Another weird routing decision was that it routed me one way to my destination and another way on the return trip. Despite these events, it gets me where I need to go and is an improvement on my total lack of direction.

I love audiobooks, and took advantage of the 3 free Audible books with the Garmin. They have a fantastic selection and I'm really thrilled to get bestsellers to listen to. My library has a good selection, but not too much really recent. Also the NY Times - really great to have the news read to me in the morning!

I thought I'd love the FM transmission feature - but I guess I didn't understand how it works. I can't listen to my car radio or CD player while its in FM transmission mode. So I don't use it much, except when I'm listening to something from Audible that I've loaded into the unit.

The best feature is the bluetooth. I don't have to take my phone out of my purse. I can make and receive calls so easily and its much safer than trying to hold the phone while driving. And I like it much better than the headphone I sometimes remembered to wear. My callers say that the sound quality is OK - not great, but as good as what I was doing before.

The TMC traffic is pretty useless - it has warned me about incidents that don't exist by the time I get to the area - and not warned me about other incidents - or rerouted me into major construction areas. I've heard MSN is better, but I'd have had to spend at least $100 more on a 7xx model, and I didn't think it was worth it for me.

The POI is really neat too - a mobile yellowpages. Really geat that I can also call with just a press of the button. Its just as helpful at home as on the road in unfamiliar places.

How did I get along before my GPS?

I have been a longtime user of Garmin products from the forerunner to other handheld products and this is by far the best I have had. I have used it in the US, France, Italy and Spain and it performed great. It even warned me when to slow down for the photoradar driving to Normandy in France.Of course, there are times when the directions get a bit confusing but that happens and is probaby more to do with me than with the unit....The one draw back is the battery could last a bit longer but I usually hook it up to the DC adapter anyway. I have used the MP3 feature as well as the bluetooth phone..all work well. The great thing too is the preloaded maps of the US and Europe...I remember downloading mapsets into my old Garmin (PAINFUL!!) and now...none of that...No regrets with this product. I give it to relatives that visit and the "Home" feature is nice so they can find their way back to us....

We bought this for a recent trip to England, Ireland and Scotland, and we found that all of the maps were quite detailed and the Garmin easy to use. All of the small roads in Ireland were even on the map, which was good since it would be very easy to get lost.

We did find it took a little while (especially first thing in the morning) for the satellite to boot up and find your location, which was frustrating when you needed to find a location and were waiting several minutes for the satellite to link with the Garmin. There were also several restaurants, rental agencies and other locations not in the system, which needs to be improved. (for example, the rental car agency in Ireland was not on the map and it was offsite like many others.)

Overall am pleased with the purchase and would recommend it.

We purchased this as a replacement for another brand unit in order to get the European maps and the battery operated portability. We used the unit primarily in a vehicle in Scotland and had coverage in all areas around the Highlands. The system was extremely accurate. The unit allows for choice of "quickest" or "shortest" routes and not "most highway use" as did our previous unit, and Garmin seems to make no distinction about the size and quality of the roads it uses to route, at least in Scotland. We found ourselves being routed on one lane roads instead of going a few minutes further to a two lane road. After an adventurous 8 mile leg on a single lane road through a cattle and sheep farm, we dug out our AAA maps and routed ourselves, then let the Garmin reroute to where we were. It was extremely helpful to have a preview of the upcoming road and to have the voice tell us about the exits and roundabout turns. It is always a comfort to know where you are on an unfamiliar road at night and that you can find your way back to your hotel, especially in rural areas. Great product, but don't forget your paper maps!

The Nuvi 670 is extremely user friendly and start-up is quick/easy. For the most part the maps are excellent and it is feature rich - specific address, city only, intersections, favorites, home. In very rural areas, you do need some idea of where you are going. My setup was to "fastest route" and sometimes - when out in the those areas - that meant being told to turn onto a farm road - gravel, dirt and all. The recalculation time is very quick and the GPS is sensitive to very short distances - maybe 200 feet or less. When I failed to turn or made a mistake, it quickly got me going in the right direction. We are just coming off of a 2500 mile road trip with the Nuvi - it was wonderful. Loved it and it saved so much time and gas in determining the best routes plus finding gas stations, ATMs, hotels, etc. If you live in California, you will need to order the friction mount since CA doesn't allow the window suction mount which comes with the Nuvi. Friction mount works very well.

I absolutely love this GPS! It is easy to use, accurate as it any specific and detail direccion can be. I used to get lost all the time, now it is a breeze, I can go to Italy and know what I am doing and where to go! I have no complaints except for the windshield mounting piece, because it falls easy when there are high temperatures (imagine, I am in FL) so, when I do not use the car in a day and I live it where there is heat, the mounting piece falls. Other than that I will reccomend this to anyone. If you want to give a woman "the perfect gift" (other than diamonds) this will be the gift you want to surprise her with.

I like the Nüvi 670 very much. On a recent trip to England, I used the included suction cup mount and cigarette lighter adapter to mount it in my rental car. It was invaluable in getting me from point to point while I concentrated on driving on the left side of the road and navigating the roundabouts. The pedestrian mode was very useful in helping me get oriented after I emerged from underground subway stops. Its pretty clever that they thought to include a mode that ignores one-way streets and illegal turns for people who are walking. The interface is fairly intuitive. The Bluetooth integration works very well with my RAZR. The MP3 player is quite adequate. The picture viewer is useful for a small number of pictures. I would prefer other ways of navigating through images for larger numbers of images. I also found it a little slow when dealing with 10M pixel images from my camera, but that is to be expected. It certainly works well to have a few family snapshots available to show friends, but it fall show of being a good way to review pictures on a 2MB SD card while on vacation. I like the simple USB interface to my Mac. It makes it easy to get files on and off the Nüvi.

Overall, I'm amazed at how much information I can hold in the palm of my hand and the number of things this device does well. I give it four stars instead of five only because of the minor issues I listed so far and occasional hick-ups in the database in the EU. For example, it was able to guide me to the rental car pick-up at Heathrow airport, but not the drop-off. Also, the FM transmitter is not very strong and doesn't not work well in my car. These issues were only minor for me, but make it slightly less than perfect.

We have had in-car GPS units in my wife's last two Infiniti FX 35s and I always considered them the benchmark for in-car navigation but the Nuvi 670 is clearly superior.

I use the 670 in both my BMW sedan and my Porsche 911 and it is markedly better than the in-car systems offered by either of these manufacturers.

So far it has performed flawlessly. It's easy to program and the maps are nicely detailed. An easy-to-use menu system lets you quickly customize the unit's functionality to your personal preferences. The included windshield mount puts the unit up where your eyes should be - watching the road and traffic - not down at dash level.

The traffic alert system works just fine in my area and it is a terrific help in avoiding delays. The traffic data links up to the 670 through a special power cord that includes an FM receiver.

Don't lose this cord - the replacement cost is north of $200! A standard vehicle power cord is $30 and is what I use when I take the unit on business travel or vacation trips. After the initial trial period the traffic alert service costs $60 for an annual subscription fee.

The unit updates over the Internet via your computer and thanks to a recent software fix it is both PC and Mac friendly.

I plan to use the 670 both in-car and - thanks to the battery and built-in maps for both North America and Europe - on foot in Italy this summer. This wouldn't be my pick for a back county hiking GPS but I'm looking forward to seeing how it helps me get around Rome on foot.

When you factor in the other features Garmin builds into the Nuvi that go beyond navigation (Photo Viewer, Bluetooth link, MP3 player, SD card slot, etc.) and the add-ons and accessories available you have the Swiss Army knife of portable GPS units.
