Audio Systems: Aux Input, sirius sportster 5, auxiliary input adapter

Question
I have a factory installed AM/FM stereo/ single CD sound system in my 2006 Mustang. On the front it has an AUX button.  I recently had a Sirius Sportster 5 with vehicle kit installed using the FM frequency which is static bound.
Does the factory stereo have a direct connection jack that could be connected to eliminate the FM transmission problems?

Answer
yes there is a plug in the back for that the audio quality will be like cd and no static
you need the harness and interface for the FORD radio
