Ah, I have an Equinox EV and it will automatically precondition based on the on-board maps, which, in my case, is Google Maps. I don't have the luxury of Android Auto or Carplay unless I jump through some hoops and self-publish an app in the Play Store. And even then it is janky.

Even so, I have a button in the battery settings which can start the preconditioning whenever I want to. It's been a fantastic car, but I am envious of your DCFC capabilities. But not of your ICCU. :-)
