There are some areas in the world where Google Maps is totally unreliable. Here in Cyprus are roads in Google Maps which are only for good 4x4 cars, sometimes also totally wrong and the best part: You cannot report wrong things in Google Maps in Cyprus to Google. So no chance to correct it!

Many tourists drive with their normal rental cars into very remote areas.

So at the end I use OSMand+ (Openstreetmap) always and Google Maps only for searching.
