Mine does. Well, I don't know about France, because I haven't been there
since I've got a savnav, but it does show speed limits in Germany and

But there are two caveats: 
  1) It doesn't know the speed limits of all roads. Not showing a speed
     limit doesn't mean there's no speed limit, it could also be it doesn't
     know the speed limit (most of the time it doesn't know the speed limit,
     its for city/town streets).
  2) Speed limits change. 

It's pretty accurate though, it often changes right after passing a speed
limit sign signalling a change. And it even knows about short stretches 
with a different speed than the rest of the road.
