Not a full solution, but if you do run a cable, I'd run a long USB extension cable from the back of the stereo and leave the open end wherever you choose to plug your phone in. That way you can plug a Lightning cable, or Micro USB or anything else in there, if you ever need to swap it out, or if the tip of your Lightning cable were to break, or the coating start to fall apart. Check out the braided nylon ones.
