The Sony unit was part of the 402A package on the '13 SHO, along with HD radio, active park assist (pics a place then parks itelf), rain sensing wipers, heated and cooled front seats, heated rear seats, blind spot monitoring system, and rear window power sunshade.
The Sony headunit and speaker set as well as the HD radio capability (for terrestrial and sirius) are options included in 402A. Sync and MFT are standard equipment on all Taurus models. Had to look up some window stickers to get this, I had not ever had seen a SHO without the Sony/HD until now.
