A:AnswerHello Lee, thank you for your message. When “SHUF” is selected, the system shuffle-plays all audio files on the USB device. When “FLDR SHUF” is selected, the system shuffle-plays all audio files in the selected folder. For more information, check the operating instructions in the link below: https://docs.sony.com/release/CMTSBT100.pdf. -Oscar.
A:AnswerSorry--unable to answer the question--as we are having the same trouble---going to return the unit-disappointed in sound quality and reception.
A:AnswerProbably not. Connect your hard drive to the USB port to be sure - but most hard drives will not be recognized by the Sony stereo. Solution: Buy a large capacity USB memory stick with a small form factor. Load it with all the songs it can hold, and attach it to the Sony stereo. This worked well for me.
