Hi
Been a while since posting
i have a VW polo and a Seat Arona both with sat Nav with the maps on Sd card have had no problems updating the Maps VW is easy and Seat just a mater of coping the NDS file back onto the update
I have now a A3 with the same Sat nav system with maps on SD card
I have read its not as easy with Audi as there is some file protection I assume that all map date file is the same across the VAG range as Seat Skoda and VW all use the same
Has anybody done this ?? going to try this weekend but while back up SD card before Try
