Radio clock problem

[blazzinbird]

yesterday I unhooked the battery to replace a air bag sensor. Replaced that and got everything hooked back up. Got in the Denali and noticed my clock showed ‘:’ no numbers. I tried to go in and adjust the time, and I hear a beep, but still no numbers.

It is a 08 Yukon Denali with navigation touch screen radio.

Everything thing else works but the clock, and it’s driving my wife crazy.

Ran by the stealer today. The service manager who also happens to be my friend told me to disconnect the battery and touch the leads together for 5 seconds to reset the computer. The clock uses a logic circuit he said.

Now I’m worried it will lock the radio

Mine did the same. Some interweb searching came up with this link, I used the first code and on page 2 of options it let me set the clock. When I exited the menu I had to adjust because I didn’t get the GMT conversion right but it worked.

So magically after a few days it started working again.

I was going to post about losing the time on my 2009 Tahoe LTZ when I replaced my truck's battery a week ago. I've driven a fair bit since then and still no clock so I'll try the secret keypad trick in a few minutes.

This worked for me but I thought I'd point out that reading is fun duh mental. First try when I exited the menu my clock showed 2:58 which is 5 hours too early. 5 rang a bell and I went back in to read at the top of the screen to set the time GMT. Doh. Add 5 hours since Eastern Time is GMT -5.

Thanks for all y'all do.

So our clock is showing now, but it isn’t changing times. You have to press the time on the screen and the time updates. So annoying.
