I cannot get my SD card working at all. I have a mixture of mp3's and m4a's, the structure is right, amde sure each top level folder has less than 1000 files in it. Tried the card in NTFS and exFAT format (both slow and fast formatting). The card won't recognise a thing. Put a mixture of the same files on a USB stick and that won't work either, although my original USB stick out of the Scirocco works in the car, only recognising the mp3's on it and not recognising the folder contents for an album folder that contains m4a's.
Has anyone else had issues with m4a's not being recognised in their Golf?
