I know old habits die hard, but this is one that should be stopped on these forums.
Michelin has somehow abandoned its GPS/navigation system. It has not updated its online cartographic base for smaller-scale maps (the ones who look really nice) for several countries for up to 4 years and counting. Its driving instructions, once very reliable when it came to detours, planned works and temporary roadblocks, have grown more and more outdated.
Meanwhile, competitors such as TomTom or Google Maps stepped up their game.Like all other major printed mapmakers (Rand McNally and others), Michelin dropped the ball with the "online thing".
So I think we do a disservice recommending it over other apps in 2017. I fully agree it was the best - up to 2012 or 2013, but they just gave up on development and are keeping the site alive for the sake of doing it. The Michelin travel guides are also missing updates they were known for. I used to find Michelin green guides very useful for their 'systematic coverage' of Western Europe, in the sense that if some barely noticeable monument, mildly interesting church or decent-looking natural park existed, their green guides would have a list with a website and more.
Only their restaurant guides seem to be doing really nice - for now - on the upper end of the gastro market.
