Why is the CD-Changer (CDC) mode used for bluetooth? #23

When reading through the code, I saw that the Arduino lists itself as a CD Changer. I found a document that shows different Melbus functionalities (see the "Appendix Known IDs" section at https://volvo.wot.lv/doku.php?id=melbus). I feel like "Media Device (MD)" unit is more descriptive of what the device will do. It also looks like a MD supports the same commands as a CDC. Is there a reason why MD was not chosen?

Never mind, I see that this has been discussed in #10 (https://github.com/visualapproach/Volvo-melbus/issues/10#issuecomment-346126611)
