I recently updated my Z82 to 4.40 and After finished updating I got message "Cannot authenticate maps. Contact the map content seller for help."

I tried to reinstall every maps several times and nothing changed. The message above keep popping up and the time is not sync correctly. 

I already changed PCs and got the same problem.

Need help.

Thanks

    If reinstallation of the maps do not resolve the concern, then manual deletion of the GMAP files with the GARMIN folder are likely needed > Then update resulting in reinstallation of new maps files should resolve the concern you are seeing.
