I like to listen to my music on my USB drive. I have been using it for years now and it has worked pretty well in all vehicles we had, to include a 2019 mazda cx5. For some reason, I noticed the 22 cx9 we just acquired does not play or show not even half of the music on the drive. I tried to change music titles on the thumb drive to see if maybe the symbols are throwin the system off, however, this did not work at all. Any ideas to why this is? This is the only vehicle I known to have that's done this.
