Since the media Player works with USB and Flac-files, I prepared a small portable USB-powered HDD with some music. I formatted the disc with the FAT32 file system, and deleted any files except the music files in the folders. Then I connect the drive and the car recognizes it. I get a msg that it is preparing or something, and after a little while a progress bar is moving sligtly. Before a minute is gone however, the screen turns black for a while.. and when it restarts it has forgotten about the HDD. Same happens again and again if I try to repeat it. Same with both USB-slots. Is the music index buffer so small that it is only able to handle tiny memory sticks or something? Can it be a problem with some folder- or file names? Problems with tagging in some of the files? Any suggestions?
