Within 3 seconds of turning the ignition OFF, pressing the radio ON button the radio will stay on.
Pressing the radio ON button without the ignition turned ON will operate the radio, but it will turn off in one hour sooner if it senses the battery is getting too weak.

The REST system also works without the key in the ignition.

Obviously some other systems are not shut down entirely when the key is turned to OFF or there would be no battery drain. The designers of the electrical system will have to take the RAP if the system lacks what is otherwise wanted.
