Ok, so this past week i took the car in to be serviced, and they updated it with 19.2. Well, i think that the car is a lot more responsive and acceleration is a lot better. But, after the update- i get an error message that says that data transmission failed. I tried to push the SOS button, and all that i got was my lattitude on the iDrive. Also, the bars at the bottom by the time on the screen are gone, and my portable motorola V60 doesn't work in the car either. Is it possible that the TCU was fried, or was it just shut off after the update?
