I tried installing my XC40 with the latest OTA Update. Unfortunately the update failed to install properly and now my back up camera is no longer working. I don't even see the icon button in the main screen.

I'm hesitant to do a reboot as this will be the second time in the last 3 weeks I've had to do one. First time was due to the car audio completely cutting out.

 

If it was my car I would drive straight to the dealer and tell them "Fix it!"

 

Well, I called the dealer and made the appointment and, wouldn't you know it, the next day the update re-installed successfully. Then following day, the camera software fixed itself.
Sometimes cars are too smart for their own good.
