Map update issues 2021 help please

I have just updated my VrS 2017 Mib 2 unit to 2021 map from the Skoda portal using my VIN as I have twice before.

I hit several issues 

1 i couldn't extract or copy to the card as t was FAT32 skoda card and win RAR and Windows said the file ( 6GB) exceeded the FAT 32 file limit of 4GB.

Skoda said convert to NFTS ..  did and it worked.

BUT the new maps inc 1/2 or Europe and when I ask to set a dest then I am asked which country ---- scroll to the bottom of list for UK , then chose country again !! England.

Then town before I get the pstcde .

The map is out of date as It still doesn't show the A14 Cambridge which was completed over a year ago! Speed limits are wrong in several areas.

Every time I ask for a new destination I have to go through the whole rigmarole of selecting country !

Never had these issues before.

Can anyone help or so I rip the whole unit out and fit a decent sat nav! 

I prefer sygic but it won't link to the infotainment system . I get voice but not maps.

Sick of the awful Skoda navigation 

Thanks
