Has anyone installed a Sirius or XM in a Fusion S? I have been searching, but have not found anything for my stereo. Its the single CD w/ an AUX button. I assume this stereo is used in other Fords. I hear the "AUX" button means it can have a satellite radio hooked up. Basically, I would like to do a complete behind the dash install. I had a XM Roady2 tuner in my old truck w/ a PIE adaptor. If I have to go the tuner route I will. But, I would like to control everyting through the stereo. Is that possible? Thanks in advance!
