Adjust map on GO 5000

I have the 'Europe + buildings' map on my GO 5000. When trying to adjust the map to 'Europe - central zone', MyDrive Connect says that my system is being updated, but I don't see anything happening and in the end, nothing has changed. The map's size on my device is 8399 MB, I have 150 MB available on my system plus 14710 MB on the SD card that's inside and the map's size I'd like to have on my device is 4592 MB.

Is there anybody here who can help me out?

Many thanks in advance.
