I have a 2014 GS. After difficulties getting the car to play music from my ipod classic, I switched to using a memory stick.

I have several thousand tracks in about 40 folders, and this usually works well. When I add new tracks to the stick, it sometimes happens that the car cannot see them. Is there a way to force it to see what’s actually on the stick, instead of relying on its own picture of what’s there?
