That’s what I assumed, but now I want to figure out how it chooses which one to mount.
First, it chose the internal memory and started to play a small audiobook which was the only files loaded.
Second, I “deleted” the files, but with Linux that creates a hidden Trash folder which the car found it and started playing.
Third, I hard deleted the Trash folder and with nothing it reported no files.
Fourth, I filled the internal memory with as much as I could and it played from the sd card.
I’ll probably just get a flash drive, but I’ll give it a few more tries.
