Thanks Jeremy. That's what I was afraid of. But why the heck to they have a source option for A/V? Maybe my service guy will know next time I take it in.As far as I know, there is no video playing ability in the JBL head unit. You could wire in a composite video through the backup camera feed, but it will have the warning message on the screen. It has enough trouble dealing with higher bit rate MP3s, no way is it going to play video through USB mass storage.
