Hoping someone here can help with my issues trying to update maps....I've read through this thread and a few others but can't seem to work out what's wrong.
I have one of the first boatload arrivals of the "new" Tiguan, back in Oct 2016. Looking at the original SD card in Slot 1, it's got the single "maps" folder, with several subfolders 21,22,23,24,27 and EEC. I believe mine is the DiscoverMedia model rather than DiscoverPro.
I went through the VW link posted earlier here, to download the appropriate map
Volkswagen Map & Softwareupdates
This downloaded a 6.91GB file "DiscoverMedia2_MRM2_2718_1010.7z" which when unzipped using 7zip, gave the exact same file structure as the original card, ie. single maps folder with the same subfolders as described above.
I copied the maps folder to a newly formatted FAT32 card (all using Windows), but when I inserted this new card into my Tiguan, keep getting the error message "Please insert a data medium with valid navigation data".
I've re-checked the contents of my new card and can't find any weird hidden files. I've even tried downloading the DiscoverPro file which is a lot bigger with different folder structures, but that one obviously failed.
All assistance greatly appreciated, as I'm currently on map version MRM2 2016/17
