I have the above mentioned head unit. Now there is no real AUX input but there is however RCA inputs for a CD Changer. There is also an 8 Pin DIN plug for the head unit to CD changer for controls. This plug must be in for the head unit to allow you to select the CD changer as an input. I would like to get the pin out for this so I can use the CD changer input as the input for my PC. I have no cable to test with as of yet so I figured I would see what a quick post here would yield. Thanks for any help.
