I remained on ver 3.08 currently (to have the Ford logo when opening the door). I saw that Wifi/BT uses the same chip, Wifi works ok but BT seems stuck. Tried to disable the car battery for a few hours, manually restart the Sync with the buttons on media, but no luck.enter the gears, then the help button, then the informaxjd button about the system and send a photo from the currently owned software.
I guess its something hardware…
Other than that (BT and scheduled maintenance that appears after leaving the car parked for a few hours), Sync works ok (Navi, Radio, iphone music via cable, video player and everything rest)
