I've got the deck, I love it! I have an eight gig jump drive by "dane-elec" which has worked great, but it really only likes to work when I just "drag-and-drop" ALL the files right onto the device, which is in-convenient when you have to switch through EVERY song manually. The problem is: when I put all the mp3's sorted in folders, it doesn't like to read them, it read a few- but not all, any suggestions? Comments? Help? Thanks a million! E-mail me for further questions!
