After a few hours of tinkering, some insights on the new map (2019.12).

The iGO8 software that works on the WINce operating system does not work with the new map. Back to the previous map (2019.07), and the software works properly.

The Primo 2.4 software on the WINce operating system works properly with the new map (2019.12).

Primo NextGen on Android works properly with the new map (2019.12).

I wonder what in the map can't fit the software, even though the type of map remains the same, with the fbl extension.
