Has any other C7 owner notice their navigation system clock times jump back 1 to 3 minutes? I have seen this happen everytime I check for this. It happens when you shut the car off with the radio on. Once you turn the vehicle off make a note of the time. Continue to monitor the time in the upper right hand corner of the navigation screen. Inevitably, within the next 5 minutes, the clock will make an adjustment and adjust back anywhere from 1 to 3 minutes. Anybody have a similar experience?
Never noticed but apparently it's suppose to do that,
I do not see any reference to what you are saying. The page you posted does mention updates may not occur right away when crossing over a time zone. I am right in the middle of the Eastern Time Zone. Why does the displayed time jump back anywhere from 1 to 3 minutes when the vehicle is turned off?
Are you using the "AUTO SET" function? If so, that might have something to do with the changes you're seeing; i.e., it might be bouncing around searching for a signal source to adjust the time and it's getting different values/sources (?). Make sure the "AUTO SET" function is turned off and see if that fixes it. I'm not saying this is what is causing it, but it's worth a try to see if going to the manual method takes care of it.

I don't have Onstar but I'll give this a try later today. Thanks!
