Audio Systems: 2004 F-150 + AUX Button + Sirius, ford auxiliary input, ford aux input

Question
I have a 2004 Ford F-150 Lariat Super Cab. It has the factory system without the DVD option. On the stereo there is an AUX button. I have pulled the radio and looked for a way to connect my Sirius Starmate but saw nothing like RCA inputs. Is there a way to connect my Sirius radio to this head unit and use the AUX button? Or was this button for the DVD option? Thank you for helping dummies like me! LOL

Answer
Yes that is correct the AUX button on the Ford radio was to be used with the optional Ford DVD video system, the good news is that there is a way to connect your Satellite radio mp3 or portable audio device to this factory Ford head unit,  you need the FRD04-AUX audio adaptor this will allow you feed audio in to the radio
