Did the update take the full 40 minutes as mentioned in the notes, or longer?
I hate leaving the car just running for that long - so I might chance it on a 2 hour drive I've got coming up later in the week. Though the whole turn car off, open doors, lock car, get out of car, spin around 2 times, hop back in car via passenger door instructions might be a bit hard
On the last update I think I just turned the car off after the update, went shopping and came back and things were as they should be.
