The Audi MMI system works with AAC files quite happily - what it doesn't play are any DRM'd or "protected" files - which is whar iTunes used to sell, although now you can choose to get the high(er)-quality ones without DRM instead (or maybe that's all they sell now?). Anything ending in .m4a should be fine (I've a number of albums I bought from iTunes and they all play in the car from an SD card, or the jukebox)
It won't play the .m4b format that iTunes uses to define an audiobook though but as these are exactly the same as .m4a files, you can just rename them
