Answered MISSING CLOCK ON C6 Nav Unit FIX::::

[Area Z51]

For all those that disconnected their main battery, then lost their clock on the Nav unit, a fix has been found and is downloadble to a CD-R

I know it works because I burned the file on the CD, and loaded it on my Nav unit.

Open the link to access the .KWI file.
The file you downloaded is a compressed Zip file, that has to be unzipped, or uncompressed first, before you burn the CD.
Once you unzip the file burn the .KWI file onto a CD-R
Follow these instructions:
Burn the LOADING.KWI to a BLANK CD-R. Once this is completely burned and finished, go to your Corvette

#1 Make sure the vehicle is outside and the engine is running.

#2 On the radio display, press the Open/Close Faceplate Key

#3 Eject the map disc by pressing DVD Map Database Eject Key. Insert the Software Update CD-R Disc in the DVD Map Database Slot

The update will start automatically. You will see a progress bar on the screen. The update takes about 2 minutes. The vehicle logo will be seen once the update is completed.

Once you see the Corvette logo, remove the update disc and REINSTALL YOUR MAP DISC!

You will see the clock now also appears on the Corvette logo Splash Screen.

Good Luck.

@Wayne07Z51 you shouldn't need the disc again, as the new firmware is now installed, replacing the old firmware.

What you mean by the battery disconnect problem?

I meant when I disconnect the negative cable in the fall and reconnect in the spring if the clock will work again, but you advised updating the firm ware this should not happen again

@Wayne07Z51 Correct. I haven't disconnected my battery to confirm this, however, a number of others have and the clock worked.

For anyone with the CDR maybe pay it forward like I did.

My nav unit lost its clock when I replaced the battery last year. Three days ago the time just appeared again in the top right corner. Works fine, just like it always did. I didn't do anything to fix it or change anything at all. Very strange!

@Laticsfan the clock can reappear and it can also disappear again from battery disconnect so the update is worth doing.

Ok will do, thanks.
