Clock quit working on factory Nav.?

[02Lightning]

My clock quit displaying on the navigation, then came back but would not display the correct time. I found the secret screen online. You have to go to Menu, display, then hold your finger on the lower left screen, a menu pops up, and you put in code 295660. I did all this, set the year and clock time in the clock menu. Well this morning it was like 6 hours off time. Has anyone run into this? Not sure what to do next?

Anything else electrical not acting right? Battery and cables ok?

Everything is good, new battery about 6 months ago.

i would check the ground wires

it's a daisy chained, its mess... you can see how dirty this one is

it's caked on with dirt 10 years worth

also the wire strains are pulling apart

this is the one that is connected to the engine to the chassis

Cables ok? Especially negative at chassis? There was a thread on here a few months back for the same thing but I can’t find it

This is normal, I have to use the secret menu too and the next day it is off by 6 hes, just reset it normally now and you'll be fine. It's a weird software glitch.

What time zone are you in? I know that on my 2005 nav radio, if you set the time manually in the service menu (not the clock menu in the config screen), you have to set it to GMT and it will then automatically compute the time for your time zone. If you are 6 hours different from GMT, try setting it to GMT.

I set it to GMT, seems to be working now.

GMT -5 or just GMT? That’s an odd one for sure.
