With the Mercedes system it sometimes doesnt tell you where to go until you are within a few meters of the roundabout and then tells you to cross 3 lanes of london traffic to get to the right lane.

That's one area where the built in nav in my car scores highly. It gives good prior warning of the next turn. It will say "Prepare to turn right" or in built up areas "Take the 2nd/3rd turning on the left" etc. The faster you are going the more advance warning you get.
