After using the Nuvi 670 for a few months I will have to say that it is wonderful. This is the only driving GPS I’ve owned but I’ve used numerous built-in ones and rental car ones. There is much to like about it. The traffic option is good but quality varies by location. The map does appear to be just a bit behind when you’re driving too. I have not had the opportunity to use it Europe, just in the US.

Would I buy it again? YES!
Here’s a quick list of the Pros & Cons

Pros

  • Reception from satellite is very good and is acquired quickly
  • FM traffic information is useful
  • Very easy to use intuitive interface
  • Directions spot on
  • Voice directions loud and clear (although some mispronunciations)
  • Big clear display
  • Very compact for the amount of functionality it provides and the screen size. It fit right in my pocket. I wanted something with a large screen and if you don’t need the additional functionality and looking for more portability go with the 370 series. I wanted the extras since I’m planning Europe trips so I’m fine with the extra girth.
  • Bluetooth functionality works great with my slvr l7.
  • It’s good that they made their connectivity using mini USB rather than some proprietary plug.

Cons

  • Merchant database is a little old in some areas
  • FM traffic information could be displayed a little better
  • Searches for some merchants never return
  • FM transmission audio quality is REALLY bad (Believe all the reviews, it’s THAT bad!)
  • Speaker seems too soft to receive calls over unless you have it mounted quite close, not sure if this is a function of the unit or the phone on the other end since directional instructions come through loud and clear. Also I haven’t tried receiving through the FM transmitter
  • My Garmin Quest seems to have a little better routing algorithm than the nuvi. The nuvi tends to try and take side streets rather than use freeways even with all avoidances turned off. I haven’t really tested this much, it could just be me.
  • Disabling the Europe maps doesn’t seem to affect startup times too much.
  • For the asking price would have been nice if they included some extras like the language dictionary, but I’m not sure what the margins are on these things.
  • Would be nice if you could change the number display subsections to whatever you want. On my quest I can customize the number readouts to show things like total distance left, speed etc. Don’t seem to be able to do this with this unit and this is an annoyance since it displays the time left which is often wrong and ultimately not that useful. Hoping that Garmin will release an update for this.
