So...umm.....my clock is working... - CorvetteForum - Chevrolet Corvette Forum Discussion

C6 Corvette General Discussion - So...umm.....my clock is working... - I heard something about the blank clock problem being fixed at some point. Has anybody else noticed their clocks are now working? How did GM fix the clock without me downloading anything to the nav/radio, I mean this radio is...

Thanks for all the replies on this question, appears from the discussion notes that due to the car being a model year of 11 years I may get the clock to work through the GPS or not? So technology is great, when it works. Now I remember car clocks were never reliable back in the 50's & 60's being manual. Having said that technology still hasn't fixed that by going electric in some cases (this in particular). Example my 09 Taurus Limited has both a separate electric clock and a clock as part of the radio and both never fail. So in some ways we haven't gained much progress. Never mind we didn't buy the vette for the clock did we. VAAAROOOM.

I have an 06, with Nav/GPS and my clock still works OK, although I "never" disconnect the battery, just leave it on a Battery Tender all hibernation period. Even when I have disconnected the battery, it has always come back.

In the US forum, there are many threads on this, and apparently, any C6 with GPS that had the battery disconnected after Dec 4 2018, is having this issue.
GM is aware of the problem and is working on a software fix.

For those that the clock is still working, do not disconnect your battery or you will lose the clock on your Nav.

One can purchase a device that plugs into the cig lighter that keeps car accessories powered up when disconnecting the main battery

Up date on the above: It is now working as of Yesterday 05June2019. Welcome to York Electronics Online. They advised that it was a GPS issue and those of us effected virtually had to wait until the GPS was repaired.

LOL. You gotta hate when the answer is to drive it out of the garage and into the "world".
