AUX adapter recommendation
 

I am trying to find a AUX (stereo) adapter for my factory premium single-Cd/Tape/Radio system installed in 2011 Grand Marquis. It looks like this is the same radio as for 2009 and 2010 models with unused SAT button on the front panel. Does anyone know which model may fit or knows the back panel connections for this radio? I appreciate your feedback. Thanks.
