Hi, I got a 32GB USB flash drive for all my music. I put on a bunch of MP3s, encoded at 128kbps, fixed bit rate, but the songs keep stuttering during playback. I had the same problem with a stereo in my Jeep, and found out they supported only up to 4 or 8GB USB sticks. Has anyone else encountered this? I see nothing in the downloaded manual about MP3 format preferences or USB size limits.
