Boot Your Car Computer on a Schedule

To get your in-car computer to do work when the car isn’t on, you’ll need to get it booting on a schedule.

OnStar, a service that comes preinstalled with certain U.S. vehicles, allows you to call a live person over a hands-free cellular connection to obtain a variety of concierge services, such as reservations, directions, and roadside assistance. One of the features of the OnStar computer is that, if you get locked out of your car, you can call them, and within 10 minutes they can unlock your car by sending a code to your OnStar system. You have to wait 10 minutes because this is how often the OnStar computer turns on to “phone home,” making itself available to the OnStar mother ship through a cellular network.
