In France, Google maps is set up by complete morons. The manner in which they give audio directions on Google maps is completely worthless in France. That's because the Google approach of using road names does not work in France.
In the US, at an intersection, you see a road sign - Frederick Road - so google says "Go left at Frederick Road". The sign is obvious and clear.
In France NO ROADS ARE NAMED WITH BIG SIGNS. They have at most numbers. If there is a name of the road, it is a small blue plate located on a house usually in a place you cannot see while turning.
So Google Maps will say "Take Rue du St Louis at the next roundabout". Well, nowhere NOWHERE is there a sign for "Rue du St Louis". There may be "D56". There is a sign for "Audierne" and so forth. But named streets? They do not exist on French road signs.
So, when driving, pay very close attention to "Take the 3rd exit from the roundabout". But the name of the road is useless.
