Hi. I’m a newbie, having just bought my first Audi. A 2025 A5 Sportback and I’m loving it. The only problem I’m having is trying to play music on the B and O system from a memory stick. I checked some things out already and found that the Audi MMI system doesn’t like memory sticks bigger than 32gb so I bought a 32 gb memory stick and formatted it to FAT32. The music is all formatted to M4A so is not DRM protected. It plays in my wife’s car, a Peugeot 2008 GT. Any ideas will be gratefully received. Looking forward to all your knowledgeable suggestions.
