Navigation data not valid

[siemic]

Hey all,

Ive retrofitted a 5NA035045D into my 2017 Tiguan.

Its mostly been fine, Carplay working etc. One issue Ive been having though is after 1 min of the car being on, the navigation/gps shuts off and gives me error Navigation data in infotainment system not valid. Check data

So I tried to update the maps, downloaded the latest from VW Navigation maps update. Put it on a fresh new SD card formatted to exfat (and tried ntfs/fat32) Placed the contents of the nav updates, so USB looks like this:

mib1
mib2
metainfo2.txt

Then after loading the contents, SD card is read successfully, but after clicking MIB Navigation Update (i think that was the wording) it hits me with a screen that says Select device

But the start button is greyed out. With a bunch of the contents that have NA or ERR or F

Ive tried 2 different SD cards, with different update files too. No luck, any advice?
