I recently got a 2017 Model S, and I need a portable CD player that will play through the car sound system. There are some things on CD, like work materials and library books, that I can't buy, download or burn to my computer. I have seen portable Bluetooth CD players, but reviews for at least one of them said that it would play through a phone or tablet, but not through car audio. I'm willing to get something that would plug into a USB or other outlet—it doesn't have to be Bluetooth enabled. Any suggestions?
