I brought mine in for maintenance and they did it then, didn't take long. It's just a software update. Came home to the letter in the mail about it, amusing timing.
This may be a tangent, but it may be relevant; My lens went cloudy on the backup camera of my Gen 3. I didn't like the $600 price tag for the OEM (minus installation) so I ordered a third party one online, (3 times, because none of them worked).
