tks guys.
In my 1240 I've only 1 map (Europe 2013.41) with Italy only (approx 400Mb) + JCV (as I've installed the modified firmware to have this feature working) + world basemap.
The issue is that this problem arrived all in a sudden after a map update (from 40 to 41) but also reverting back to previous reality is not solving the issue.
I'll try the suggestions in this topic tonight and let u know.
Tks!
