For me, I default to outside air. When I switch the car on, it retains the same setting. When i switch on the AC, it switches to recirculated air as the default setting. When i turn off the AC, it goes back to my previous setting, which was outside air. If i turn on the AC and hit the outside air button, and then turn off the AC and turn on the AC again, it retains the previous setting of outside air.
