How do you tune the FM frequency on this transmitter? Can Soundfly SD start playing from same point where I left when car gets turn off-on? 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.
