Edge 1030 plus fw 4.0
Setting
In proifile -> Navigation -> Map -> Map Visibility -> High Constrast
Now is cursor big and good readable.
After switching the device off and on is cursor small and black, with bad visibility.
To restore the correct cursor size, you need select another activity profile and then return to the one you want.
In Edge 1030 fw11.0 everything worked fine. This is probably a firmware error.
