Well, today I deleted save folder and sys.txt.
Uninstalled and installed iGO again....same problem, after calculation freezes at the "start navigation" screen.
Cannot tab the button cannot do a simulation also, only force close the app.
Renamed the mapfolder into map---2024Q2 and back to 2023 Q4......everything normal again.
So I think I did everything possible.
iGO Nextgen 9.18.27.687519
