Thanks for the info.The official Seat Navigation page is generally static in the text, just the files it links to change and then that is always behind what is on VW and Skoda servers which is why we look to them where you have the where with means to do an update if you have Mapcare, work around or retrofit.
Reckon the released SD cards will always run a month or more behind the release on the servers. That's why new cars get released with the map SD card to follow or one that isnt deemed to be current and people weedle an upgrade out of the dealer.
If the package is open I'd expect the year of release to be readable on the SD card. Not familiar with Mib1. You could download the latest update to Mib1 I made reference to and have a look. Was linked on that German Skoda board but I didn't repost here given the success of using Mib1 standard Mapcare updates is about zero in the UK.
The SD cards must be on a parts catalogue which would sort it out as well. Ekta links.
Well I swapped out my old SD Card with this brand new one and got the "checking navigation data" screen for about a minute but when that was complete the Nav data basis remained 0021 ECE 201 as before
Have emailed SEAT in the hope that someone on their parts team can give me a definitive answer as to which SD Card I should in fact be purchasing for my Mib1 unit.
