Wow! We've had a GPS unit in an auto for a couple of years and needed a portable unit for an upcoming European trip. The 670 has both US and European maps. If the maps of Eurpoe are as good as what we have seen for the US, it will meet all of our needs. It is very easy to use. Navigation commands are clear and timely for driving. The displayed maps are easy to read and to change scale. Overall, this is an excellent unit and is much more capable that the fixed unit in the car.
