Ok I put in a new Clarion dvd player in this guys 08 GT. I hooked up a ipod connector to it..thru the square plug on the back of the radio, but for some reason it wasn't getting any power. So we told him just to use his usb cable for now and we would order him a different ipod cable that goes thru the usb port and has 3 rca outputs for sound and video. Has anyone else had this problem with the square plug?
