You will have to research this but this is how...
Go back to dealership, find a car just like your except it has what you want,write down its vin number
Now go to www.fordparts.com
Plug in YOUR vin number, go to Category of Electronics and Telematics then select Mobile Multi-media, print everything then pertains to radio.
Now plug in the other cars VIN number do same thing and see what differences there are
My bet [I could be wrong] is that it is the WHOLE module has to be changed to get what you want it is just not adding a module
