Does anyone know what format playlist is needed for a Pioneer head unit (DEH-X6850BT)?

 

Playing off a USB drive.

 

The Manual says m3u lists aren't compatible but doesn't say what playlists are compatible.

 

I have media monkey and WMP avilable.

 

The quick and dirty solution is to create a playlist folder and individual folder within that and duplicate files within them.  But I have limited scope for that as the USB drive (64GB) is reasonably full.
