Garmin Nuvi 670 I have been looking at the 670 because of the European maps, but my question is can I also use this when walking as well as in my car? The parking is Europe can be hard to find after you have found where you are going to. Can you also retrace your steps to the parking garage?
You can use this when walking -- there is a setting you can change to make it 'walking' rather than 'vehicle' or something like that.
There is no cookie crumb feature, but there is a "where am I now" feature -- when you get outside the garage and can get signal, just use "where am I now" to create a favorite point, and create a new route back to it when you're ready to go back to the car.
