Thank you, I've downloaded the latest update from the given link. I then made a backup of my original Seat map SD card (or better: the genuine card with the CID but in the meantime updated map material over the years) and extracted it onto a fresh 3rd party SD card (correctly formatted, correct cluster size). It did NOT work, the card was rejected. So apparently the "NoCID" patch I applied when updating my software train in the MIB2 to fix the clock bug did not really work and I still need the original card.
I then deleted the "map" folder on the genuine card, unpacked the contents of the latest and greatest update et voila: Everything worked and I now have the latest map pack.
Thank you!
I still have a couple of questions if I may:
* Is the overall.nds tied to my VID/Serial of the unit or is it version specific? What's in the file?
* For applying the latest update, I did not need to copy over the overall.nds file from the last state of the genuine card, just used the one which got unzipped from the downloaded archive. Is that working because of the card being genuine and the CID serial number is used? The overall.nds file I had on my genuine card is probably long gone anyway during the various version updates. I never had to backup/restore that overall.nds file when doing an update so far. My Seat Alhambra is from 2016, so long before that lifelong FEC where applied if I understood correctly? All I did was copying over the maps folder all this years.
* If my genuine card is accepted, why does the overall.nds then matter at all?
* I didn't need to add any new FEC, so this is not always necessary? It seems to be a part many are struggling with according to this thread?
* I just checked my FECs, I don't seem to have the lifelong FEC 073000EE active nor available in the info menu I get when I press menu for 10+ seconds.
* In these yearly updates, is this just the map data or is there also a navigation software update included? Any functional changes?
* Where do I see the separate version of the navigation software if there's any? Are there any change logs of the software version?
* If software versions of the navigation system are NOT part of the map updates, where do I find those? Is it worth updating for my old car or won't recent version run on it anyhow?
