Just bought a brand new 2012 Outback 3.6R Limited with the Harmon Kardon upgraded audio system. I tested the USB port at the dealer with a memory stick that has lots of computer files and few audio files. The audio kept cutting out. Now I own the car so I purchased a new 8GB USB flash drive and copied only a few audio files to it. But it's doing the same thing. It plays for about 5 sec then cuts out, then plays a little and then cuts out. It does this sitting in the drive way so it can't be due to bumps. Anyone know if this system is supposed to play files on a regular USB thumb drive? It almost plays them so I figure it was designed to do so.
