a couple of guys on the caddy forums are also getting their clocks back randomly. no rhyme or reason why, while others are just getting more pissed by the day. gm is screwing the pooch on this one, big time.

Definitely weird that some are working again and some still aren't. Anyone disconnect their batteries recently and not have any issues recently? I don't want to mess with my battery

Pretty sure the only ones affected are the nav versions. The other ones (one or 6 CD versions are manually set.). The nav versions get the time info from the GPS info, and the car is not able to translate at this point.

My 05 (non Nav) has the 6 CD, manual adjust clock and the climate control panel occasionally 'glitches' where the screen blinks or goes completely blank. I started to replace it twice over the years but eventually, it returns to normal. I think your issue is different from mine. Imagine that, an 05 with electrical issues. The next thing we will discover is dead battery syndrome!

There's now a fix! I wrote to the Tech Nerd at the Corvette Magazine and they offered the solution. I did it in seconds and clock and nav system work perfectly. Go to renowned corvette mechanic Paul Koerner's website: www.thecorvettemechanic.com. There will be instructions to download a CD - he provides step by step instructions. You can also take your car to any Chevy dealership and they should be able to take care of it in minutes. If any of you subscribe to the Corvette Magazine the letter and fix appear in the April 2020 edition pages 22-24. Good luck!

My clock wouldn't set in my Z06 either. Nav w/ Bose
I read the manuals, followed the instructions, made sure GPS was active - nothing.
So I did what any reasonable person would do....ditched the ACDelco head unit for a quality Alpine.
I'll be darned, clock displays!
