Dealer updated mine to 2.9.12 when I was in back in mid-December.. it's terrible... made my autopilot unusable when going down a hill... literally slows my car down from 55 to 25 every single time... going back next week to hopefully "update" the firmware.
Be careful what you wish for with these minor updates... I am wishing I was still on whatever version of 7.0 my car was on before... :/
