I am trying to understand the audio firmware when using a USB loaded with audio files. I have on a USB over 2K music mp3 files. If I have all files listed individually and when active in the car it only presents 255 files from the middle of the file listings. Why will it not display all 2000+ file names? If I organize all of the files into sub-folders such as the Band or Performer then the 707 files are all listed with no issues. How does the random function work? Despite having 2000+ files the selection seems to bring the same music file repeatedly every 6-12 files. Can you tweek the firmware? Thanks, Brian 2014 Prius V Unknown firmware version
