Good Afternoon,

I just got a 2013 Spyder St and thus far it is a dream. I am trying to see how I can change the filter for the horn but the thing that is driving me most nuts is finding the location to connect the audio cord. There is a picture of it in the trunk but I wasn't sure if I needed to buy a cord or is this something I needed to have added. The radio works fine, but when you leave your city no more radio so I would rather just play music from my phone if I can figure out where the input is and where is the cord located.

Thank you
