To my knowledge, the 2013 F10 and some later build of 2012 F10 has the newer navigation system (HU_NBT module), while the earlier 2012 builts have the older navigation system (NU_CIC)... Me myself have the old CIC... Bad news is that the hardware between the two are physically different, and so to upgrade to NBT from CIC would require an extensive hardware retrofit and software update. And this would cost thousands of dollars
