The information was shared by an enthusiast who was digging into the new firmware with the number 2020.48.26. The system mentions two services: Apple Music and Amazon Music. Unfortunately, they are not active yet. Most likely, they will be included in the next software update.

Tesla has been rumored to have been working on Apple Music integration for some time now. By the way, Porsche is the only company so far that has added Apple Music to its system. It is available in the Taycan electric vehicles.
