How do you change clock on 2011 Chevy Impala?

Answer 1

Turn the radio on. Took me forever to figure that part out. Once it's on, press and hold the clock button located under the RDM button on the left bottom side of the clock/radio display. The hour button will flash and you can set the time from there using the radio controls. Click the clock button to move forward after setting the hour, then minutes. It will beep when set.
