Hmm, really have no idea since nobody has updated theirs with an aftermarket one yet. I assume the aftermarket powers that be has taken this into account and would try to integrate the hvac fan into their display.
And....that's why I will be ordering the touring. High end sound system, and everything you could want right in the factory display. Thankfully most new car sound systems are so much better than the crap OEM audio of yesteryear. Used to be you HAD to buy an aftermarket head unit/speakers if you wanted decent sound in your car.
