If the clock on your 07 Tahoe seems to disappear you might make sure that you don't have a MP3 disc in the radio /nav unit. If you do removedisc and restart the Tahoe. You now have your clock back!....... Clock will show up if MP3 is inserted but will disappear when restarted.. (This only applies to MP3 discs)........J.J.

 

stange, i dont have this issue and have an mp3 disk in at all times.

 

Me too.

 

Look's like another quirk for the folks at GM to solve! ......J.J.

 

Anyone know if there is a fix for this problem? It started doing it to me today and it really bothers me.
