The steering wheel and dash were part of this change

Officially with July production, but rumor has it some late June builds had the new dash but not the new steering wheel (or it was the other way around). Either way, as of July that is the steering wheel.
Of note, my friend has this steering wheel in his 550 and does not like the layout at all. Prefers the old one.
