content: Since the 670 is a discontinued model the price reduction on Amazon was tremendous. For less than $320 you get the following features- Spoken street names (although they often indistinguishable via computerized voices)- Bluetooth cell phone reception (with a bluetooth phone which works very well)- FM traffic monitor (of limited usefulness)- US/Canada & European maps (relative up to date; for the latest maps you get one updated map free and the other must be purchased)- Car & a separate home recharger- Front Window mount- Close to 6 million POI's- Car/Truck/Motorcylce/Walking modes- One way point before end destination- Old style flip antenna (instead of built in)- Very bright screen- Speaker could be louder-I took the unit on a recent trip and it was at least 90% accurate with recent (within the year) roads and freeways often not given. Highly recommended.
