Do I use less data an a Google downloaded map than on a live map?

If I download a Google map (of say, Paris) onto my iPhone and then use it for directions (e.g., get from the Eiffel Tower to the Gare de Lyon) within the area of the download, do I use any data during those directions? If I do, is it less data than if I were using Google maps "live"? (If I don't use less data, what's the point?) For example - most radically - could I turn cellular data off and still have functional directions? I suspect not, because it has to know where I am at any given moment. Thanks.
