On my wifes mustang, she has an aux input that she can plug in an mp3 or Ipod. My truck has an aux button on it, but I cannot find the input jack. Where is it located on the 07 King Ranch?
I have an 05 Lariat with the 6-disc changer, and it came with an aftermarket plug-in for iPod/MP3. It plugged into the back of the head unit. I've since replaced the factory head unit with an aftermarket one, but I'll check to see if I still have the iPod/MP3 interface and post the brand/model number.
