Can anyone tell me why my clock resets? It seems to do it after the truck sits for like 8 hours. It wont do it everytime but it does it often enough to be a pain. My radio presets dont reset just the clock. The truck is a 07 LBZ. Thanks for all of your help.

Check to make sure your battery connections are clean and tight.

X2 - It may be time to start looking into replacement batteries. My clock did the same thing, and I replaced the batteries shortly thereafter.
