I just got my 21 Plate Kodiaq, obviously no more SD sockets sadly. so I bought an SD adaptor to USB-c and plugged it with the SD card that worked in my old Kodiaq expecting to play music that way. ( I don't want to use BT or a streaming service hard wired is always better IMHO). All I get is media not recognised Any ideas what the problem could be? I tried moving MP3's to the root directory but it still didn't change anything.
