After a year of sitting in the box, I finally hooked up my new Kenwood DDX516 today. I also installed the Kenwood KCA-IP302 Ipod cable. My issue is that the 3.5mm Ipod audio input in the rear of the HU is defective. I'm only getting sound out of the left side. The unit is out of warranty so I'm looking for a work around to get this going. I dont need to control the ipod from the HU. I just need a good digital signal from my ipod to the HU. Could I just hook up the ipod to the usb input? Could I use the RCA's in the back?
