Does anybody have any info as far as getting the a la carte subscription for ford add-on units? Basically it's the legit ford tuner added onto a 2011 mustang to use the factory radio controls. I asked Sirius and they said no OEM units can do it, but add-on's can... so mine is kind of in the middle? I want to give them my radio ID to see what it comes up as but I don't want them messing with the 6 month trial period i get.
