Question for you and pardon my ignorance: This web site shows what updates are installed in your vehicle, or what updates are available for your vehicle?
I'm sort of questioning this as well. A history
based on a VIN would indicate what has been done to a vehicle and what not is pending IMHO. Mind you, the lack of an assigned CVN number could indicate that the update has yet to be performed.
Great information BTW!
Here is an example of mine.
