USB thumb drives and DNX8120

I have a kingston 32gb thumbdrive which has .wav files on it in folders organized by band. I hooked this up to a dnx8120 to test the usb play setup and it does not recognize that any music is on the drive. When I hook it up to my PC everything is fine and the music will play from the drive. Am I doing something wrong? I converted these .wav files from .flac files to keep the highest quality which is why I'm not using .mp3. Please advise.

-Thanks

Is there anyone here who uses thumb drives to play .wav files on their head unit that could help me out?

The 8120 won't play .wav files through usb. It will only do aac, mp3, and wma. In an automotive environment, you'd be pretty hard pressed (read: almost impossible) to hear the difference between an mp3 encoded at 256 or 320 than you will an actual cd. I would just re-encode to high bitrate mp3.

I've been using the 8120 USB since I've had the unit. IMO, USB is the wave of the future. Why would you have bulky old CDs in your car anymore? What I want to know and what I can't find out is: How do you search forward or backward into a song? In the old days you'd call it "fast forward or rewind". My wife's cheapy Honda Fit does it just fine.....STOCK! Am I to understand that Kenwood doesn't know about this special feature?

I have a DNX571HD and the issue I'm having is getting the folders to show in the selection menu, the music will play in order from one album to another but some will not show in manual selection menu.
