2007 Cadillac STS - Clock Reset After Batt Disconnect

After having battery disconnect for a repair, I’m unable to reset my clock. I can get to the screen where I’m supposed to be able to do it, but none of the touch screen buttons work. Help!

My first guess would be that you need to enter a reactivation code. Look in your owners manual to see if I’m right.

While that might appear to be the case, nothing in the owner’s manual addresses that. It only has basic instructions as to how to set the clock.

Is this what you did?
