Doesn't say what it's for. Doing it now.
GM really needs to fix the update system.
When an update has been downloaded it notifies the driver and if they don't notice when they shut off the car, then the radio stays on after the car shuts down draining the battery enough to signal the car not to do the install until the battery is back to 100% charged. Not a huge deal but it means you have to either take the car for a drive or put your tender on the battery for the next start.
