I have been working with m3u_creator_acp.zip which becomes a .bat file that when placed into a folder (in my SD card) with mp3 files will create a playlist.m3u file. So far while testing this I have placed two folders on the SD, with each folder containing two songs (mp3 formats) copied from itunes and the bat files has created a playlist.m3u within each folder. I then placed the SD card into my car (MB C300 with Comand,) and it showed two playlist.m3u's...both named playlist.m3u. So to distinguish the two different playlists, I renamed them on the SD. However, the car's system still came up with "playlist.m3u" for both playlists and not their new names. And, this is where I am stymied. Any help here?
