One of the things I notice CarPlay has access to is the fan speed. In one of my vehicles, when I say “hey siri” it turns the HVAC fan down so it can hear me better. I’ve always wondered if the interface is the phone telling the car “hey make things quieter” or if it’s explicitly turning the fan down. It’s also interesting that this only happens in one of my cars. I assume it’s because the other car is a higher end vehicle and has a quieter fan. | |||||||||||||||||||||||

In GM cars (as observed in my last few), the logic is in the head unit: "mic on -> hvac lower", while "hotword detect" uses a different "mic on" method that does not EDIT, previously "does not" above said "doe snot", which explains the reply below | |||||||||||||||||||||||
