Summary: Garmin nüvi 670 4.3-Inch Widescreen Bluetooth Portable GPS Navigator My nuvi 670 works beautifully in the USA but a nuvi 360 would work just as well for half the money. I purchased the 670 for a three-week vacation to England last summer. The 670 failed miserably. As soon as I received the 670, I ordered the free update CD with European maps and loaded them on my Garmin. I thought I was all set.
Cons: FM transmitter does not filter out background noise (my separate FM transmitter does this very well). In my area it's very hard to find a frequency which has no radio noise. To me the FM transmitter is important since device has possibility to play audible files and mp3s, for which the internal speaker is not good enough.
Summary: Another poster below - who doesn't own this product BTW! - bitterly complained about how GPS in general 'route in a zigzag, makes you hit every toll-road', etc. RTMS! Most every brand of GPS, this Garmin unit including, will allow the user the customize routing preferences. In the case of the Nuvi 670 hitting the wrench symbol on the initial screen invokes the configuration window, then clicking on Navigation will allow to customize, among others, Route Preference...
Pros: 2 for 1 deal: US and European maps in one unit, large screen, portability, excellent support.
Summary: Bought the Nuvi 670 for a trip to Italy. We were going to rent a GPS navigation from the car rental company but they wanted over $200 for the two weeks. Bought the Nuvi 670 for the balance of features plus US and Europe maps. Upgraded for free the Europe maps prior to leaving. Read several reviews prior to purchasing and had some concerns about the mapping ability based on others reviews. The ease of use is great. Very straight forward and logical.
Summary: I used this garmin right out of the box for a cross country trip from Alabama to Wyoming and found it very useful. It allowed me to be aware of many museums and local restaurants along the way. Visiting some of these "finds" made the trip outstanding.
Summary: I recently bought this unit because it has maps for the US and Europe builtin. Since I was planning on using the unit in Europe this summer, that is a much cheaper option than having to buy the European (or US) maps separately. I used it a bit in the US, where it consistently gave me reasonable routes, although, as at least one person mentioned, it occasionally will tell you to get off an interstate, and then immediately tell you to get back on it.
