You can buy them off e bay, you need a 32gb Seat, Skoda or VW card. Any one will work. We say 32gb since the all Europe map will fit on it. If not bothered about driving the length and breadth of Europe at 16gb card will do.
The cars are sold prepped to just take the card. It then pairs with the release year and period of the card. This is where you do the "workaround" discovered by one able board member back in 2017 using a bin walker. That expands the binary so they could follow the code. They isolated the overall.nds file, moving that between releases makes the contents look like the release year of the card but it isn't. Just sets a VCDS flag which everybody ignores.
If your unit has had a card in it, but lost or not working the quickest way is to go back to year dot of the Seat mib2 map release, this gives you the overall.nds file that you then move forward onto the current release. The map files are released June and November each year currently. Its all the same mib2 standard release across the three brands you don't need to use the brands release from the website. All the same file. We take them from the servers rather than the website wrapped page.
I've written
resource based on Seat users common knowledge:
This
resource is applicable to all Seat navigation systems plus other Vag brands which are MIB2 / 2.5. It is built from the knowledge base on the Leon forum from a long running thread which has the advantage of tracking the twists and turns over...

Then we have the discussion thread for it:
I had the same
problem when I updated my maps last Sunday, had to use a new 32gb card (which I already had), 2 of my old 32gb cards did not have enough space. I checked them for errors but non found. Probably bad sectors: https://www.stellarinfo.com/blog/repair-sd-card-with-bad-sectors/ The...

Both of these cover the standard release (that we are talking about) and the mib2 high release.
For the standard release we are on serial 2010 which is v17
The old release should work straight away. Failing that the new release with the old release overall.nds from year dot. Failing that try the new release with the overall.nds that came with it. If that one works it means your unit had the life time navigation FeCs on it. The production issue...

I gave up quoting year code since VAG messed up the indexing between the standard and high unit so they now don't tally. Just refer to the id of the release.
Anybody reading this
don't just delete you maps read the work around in the
resource else you loose your overall.nds file and have to go into the process of recovering it / one that works. There was a wrinkle with one release where if you lost it you really need the one before or it. Its on the thread, I've only seen it reported twice.
Be aware you are suppose to use Keka and CleanMyDrive on the SD card if using a Mac. Mac's leave junk behind in files which Mib2 units don't always take kindly to. Mib2 high map update will stop in its tracks.
I should mention there is a mib2 standard tool box that do assorted things but you need to mod the firmware for this. I've not come across anybody on the forum yet that has used it. One of the mods is to take away the need for the CID on the SD card. Given we know the workaround works to update the maps adding the need to update to a specific version of the firmware to work with the toolbox that nobody has any experience of here doesn't seem a good one. It's this firmware or similar processes that retrofitters offer to unlock the maps on the mib2 standard units, They take the CID off so any card can be used with the unit then write a long life navigation FeC to the unit.
For the mib2 high for updating the high you have the mib2 high toolbox that I've used to get a Skoda navigation FeC when VAG were playing silly billies and didnt release the map in one six monthly update for Seat. The units run happily on Skoda navigation FeCs or a combination. For those updating mib2 high units you can use a custom release called 1447 AIO (AIO means all in one). In this release it updates a mib2 high to the very last release of the firmware then runs the mib2 toolbox to update the FeCs and adds an update to Grace Notes that's never been release (album art). Good reports by users that have done this. The software was put together by a collective of European mib enthusiasts continuing the development beyond the final software release. They post on the mib2 firmware thread:
but i have other probleme in the tablete of the car i don't have icon of navigation so i think i need to change the system no? i have MU Version 514 its oky? , and when i use any sd card the car can't read that because i need nav system + when i join Green Mode there are file name ( navigation )...
