I recently put in a 512GB Micro SD card into the port under my arm on my 2020 C300 full of .mp3 files to play as music, books, and comedy. There are many, many, MANY flavors of them out there, but the key is "Micro SD Card". I think this is the example I put in my car, but others would work fine too.
