Clock Blues
OK I forgot to hook up my battery tender on my 2006 and 2 weeks later wanted to take a late evening ride. Well, yes, you guessed it the battery was dead. This was only the beginning of the problem. I noticed afterward charging that the no GPS symbol came on and the clock was missing. No matter how hard I tried I could not reset the clock. The windows were not indexing and so on. I took it in and they found that the On-star module was malfunctioning, changed out and most things started working. Except, still can not set the clock. Well the dealership called tech support and after a few days got a reply. They were told to stop trying to fix the clock. Even changing out the radio unit would not fix problem. It appears who ever developed the clock program only programmed it to work through 2018. If you never disconnect power from you corvette the clock will continue to function but if power is lost then the clock will stop working until they come up with a fix. Has anyone else had this problem?

Only 100s, including myself! It would behoove you to use the search engine for the C6 forum. https://www.corvetteforum.com/forums...isconnect.html

And the good news is: the clock may come back, but it'll do it whenever it gets ready.
You ALWAYS, ALWAYS have to reset the window indexing after a battery is disconnected, then reconnected, even if it's a new battery. It's in your owner's manual.
Here it is:

Here it is:
With the engine running and the window down, close the car door. Raise the window and hold the up switch an extra 3 seconds. Release. Without lowering the window, hold the up switch again for 3 seconds. Release. Done. Don't forget the other window.
This will need to be done to both windows every time the car battery is disconnected, then reconnected, or when a new battery is installed in the car.

I went 3 years without using a battery tender and I never had this problem. At that time I drove car once a week. The factory battery lasted 12+ years.
Why do alot of Corvettes have this power drain/dead battery problem?
The electronics?, computers, Lots of electronic options?

Perhaps something also changed in the GPS code, so our cars may be too old to interpret it, now. Like any software producer, the government may not want to keep supporting an application this old.

This particular problem is due to the age of our cars, and the way the coding was written. It simply didn't allow for our cars getting old enough to last longer than the code was written to calculate the time based on the GPS satellites signal. Similar to to the Y2K issue, but I don't know why GM would not take that into consideration by 2005.
