Can Soundfly SD start playing from same point where I left when car gets turn off-on? How does it identify, browse and show on display the various mp3 file folders on SD card ? I recently brought this device. I am not able to play my ipod connected to this device using the USB interface. Thanks in advance for your help. Comments 0 comments Please sign in to leave a comment.
