I have unchecked all other maps. There was problem on whole map. The problem started when i updated firmware to 6.10. In 3D view of the map (like when driving), map do not show all the roads. The same when i look in "browse map". When i zoom in few times in both these views, then i can see all roads right. When i zoom out, parts of the roads dissappear. All the time, most map view checked in settings. And only one map selected. In 5.90 version of firmware, everything works all right. I tried 6.20, the same thing like 6.10.

In ver. 5.x, i don't remember, there was a problem, but that time colors of third party maps was strange, black, purple, fluo green. That was fixed in one of the following updates.

Thanks to all.

I will try hard reset.
