I just installed a F700BT a few days ago and just wired up my ipod with the cord that you have to buy separate last night. I tested it out and it worked fine, but I wanted my ipod in my overhead console so I bought a USB extension cord and some RCA cables. When I plug the pioneer ipod cord into the usb extension nothing happens. Everything works fine if i plug the pioneer cord into the usb coming directly off the unit or if I plug the ipod cable that came with my ipod into the usb extension. It seems to be the combo of the extension and the pioneer ipod cable that is not working. Has anyone else had this problem or know how to fix it?
