My 2009 car plays mp3 files

Do I just drag and copy the files to a dvd as one would in windows please?

I burned the tracks as data rather than audio which was the way It was advised. You should use CDs not DVDs. I Would doubt that dragging and copying would work but open to correction. John

I think you mean for the CD player in the upper glove box, not the DVD in the rear? If so, just burn the MP3's onto the CD and all should be fine  SDV8 AB MY 2019
