Stone to sit on if mib2 standard, that's if 6P on descriptor follow link
Post 2075 on the navigation thread covers the instances where either a standard map mib2 SD card: is lost contents are deleted by accident you need to update when you want to change cards from 16gb to 32gb (for when the all Europe map pops 16gb, hasn't happened yet) or have a spare card...

If you got the card you need version 1 for the overall.nds file. Then latest maps still 1430. It's all there. Beware of Mac issues covered.
We go back to the first overall.nds file released for Seat mib2 standard since its a catch all other than that you needlessly search for the exact match of the release SD in libraries. So two downloads the Skoda 1 for v1 of the Seat card. Then 1430 off the VW site for the Nov 2019 release. Rumour Sept for the delayed June release.
BTW You
shouldn't be able to delete items off the card within the infotainment unit so it must have been put into a PC or Mac ?.
If the card says 6P on it in the red bar in small print its a Mib2 standard so instruction as above.
5F it's a Mib1 standard not the instructions above... find someone with the same card and take a copy or buy one.
Before doing either I'd suggest a long press on the volume control till it reboots then put the card in. Turn off / turn back on again so it reads the card.
You might always have a corrupted card due to heat etc if it never saw a PC or Mac and went wrong.
Obviously only works with the navigation card in.
High units you can mess up but only from the back end developers menu that you wouldn't normally have access to... unless it is a mib1. May be possible with a standard mib1 to fiddle in the backend menus.
So first one needs to know whether it's a mib 1 or 2 standard based on card serial number. Those leading letters. Put a forced reboot in, then action the rest.
