Hi all, I have a 2015 Fiesta ST - base model. I have a question regarding the Sync system. Looking online it appears the last update was in 2015. Also, I have seen some versions with Nav even without the Recaro Seats option. Question - is the Sync with My Ford Touch Nav compatible? There wasn't an SD card in the slot when I bought the car. I am trying to explore all the infotainment system's functions. Thanks for any help and I can't wait to get out and play with the car!
