yes you plug the 3.5mm jack (with 3 rca on the other end) to the AV socket, plug the yellow to the tv (video in - also yellow). the 2 other color maybe red and white or red and black. plug the red rca to red aux in and white or black to the white or black aux in of the mini component. if the mini component has a 3.5mm aux in, you have buy anothrr cable with female rca in one end and a 3,5mm jack in the other end.
once you have selected your music file or folder or drive, you can now turn off the tv, should the cocoon has no display for you to decide the said music file, folder or drive.
