also es geht aber nur bestimmten cardreadern. bei mir ging nur der Ricoh
mann muss auf die karte (orginal schreiben können)und ich habe von einen hier im Forum nur eine 2013 Maps gehabt.
Das schreiben dauert gefühlt einen Tag aber danach ging die Karte.
Hier die Übersetzung der Russen
1) backup your SD Card!!!
2) try something write to your SD card - if it is possible on your card reader (i tried 6 cards readers, only on old Lenovo X1 it works)
3) erase this card (in total commander)
4) write new maps to this card !!! This proces due to specific copyright protection take 1 day!!!
I put this card into navi and it worked !!!
I found, that in this SD card is not readable part (readable only in specific panasonic SD readers) so this part you cant delete and it is the reason, why it works in navi with newest data...
Hope that someone make more research and find, how to activate SD navi and new SD card without codes
, audi bastards charge you for lot of bugs.
