I have a 2013 impala LTZ and I can't change the time on the clock. The clock works, but I can't change the time. I've followed video instructions on how to change the time, but it doesn't work. I'm guessing the clock button is broken. Is there a fix without replacing the entire radio?

Question edited for clarity, and correct order of information and toss in a few CAPS where needed.
Question moved to model category.

All Impala are the same, only difference is bore and stroke for the extra capacity.

Press the power button. Access the clock via the menu button. Finally press the dash buttons that are located right under each display to set the hour, minute, month, day, and year on the 2013 silverado.

If the light is flashing its because your doing damage to the catalytic converter. Your dumping raw fuel, in other words you have a coil pack not firing. Your gonna have a P code. Either P0300 random multiple misfire, P301 cylinder 1 misfire, P302 cyl #2 misfire, ect... Replace the coil pack on the dead cyl.

• Press and hold the HR and MIN buttons together for two or more seconds to update the time.
• The display will show "UPDATED" after receiving the broadcasted time data. • If the broadcaster is not broadcasting the time data, the radio will display "NO UPDATE" and the time remains unchanged.

if this doesnt work, just simply push and hold the hr and minute buttons to set the time
• Press and hold the HR and MIN buttons together for two or more seconds to update the time. • The display will show "UPDATED" after receiving the broadcasted time data. • If the broadcaster is not broadcasting the time data, the radio will display "NO UPDATE" and the time remains unchanged.
