I just picked up my 144 Crew with 10" mbux. One thing I overlooked was making sure I had the auto AC feature. However, I found a fortunate glitch. As I was setting up a user profile on the MBUX, I noticed the climate display reset. At which point the fan and vent selection switched to auto (I do not have an "auto" button). The climate control now performs like it is in auto mode. If I change the fan speed or vent selection it switches to manual mode and there is no way to go back to auto without resetting the MBUX profile.
