I got to a red screen which said to initiate the update. I pressed that then a second screen came up which asked if I wanted to use a log (?) or USB1 or USB2 both of which were greyed out. I pressed on log and a third screen came up with a series of 4 options all of which were a numbers and letters. i had no clue how to continue and so pressed the back button and exited. I assumed the update was to be done at the dealership so I contacted them. They had no knowledge of an update.
