Are you using a Mac perhaps? 
as extra files are left on the SD card which the Skoda system doesn’t like. 
If using a pc. If the downloaded files from the update portal are unzipped to a 32gb SD card that’s formatted fat 32 you shouldn’t have any problems.

Same as Kenny R said above. In fact I didn't unzip my file and it still worked. Also, you don't have to use an SD card, it also works with a flash drive plugged into your USB port.

The first time I updated the maps it worked seamlessly, but on the second occasion some sort of corruption  must have happened when downloading from the Portal, so I had to delete the file and download it again.

 

Yes, it is MIB2 that you need.

Does the myPOIs get deleted when updating the maps using the above method?
