You assuming your dealer told the truth. They lie all the time.

 

Here in Alaska the NAV is virtually worthless already. There is map data for Alaska so you can track your progress but there is no POI data for Alaska so you can't set a destination unless you have already been there and set a waypoint. I can set destinations in Iowa but not any place in Alaska. The emergency locations provided are in Canada. I have to admit that when I first bought the car there was no Alaska data on the NAV discs of the time at all. After several years of complaining, Alaska map data was finally added to the NAV discs but never any POI data so you could plan and set a destination.

 

The clock issue is I've that has been sent problem for some time. Probably a firmware issue. If the battery is disconnected and then car has over 100k miles then the clock hours black and the buttons to set the clock are non-responsive.

Mine is the same thing a couple months ago and yesterday and the blue clock just started working again so there is hope out there your clocks to return. I didn't do anything special to it just looked at it and it was working again good luck everyone.

 

Mine's also not working after a recent battery change...and, in my case, "over 100k miles" has nothing to do with it as mine only has 65k.

As for me...having no clock is no biggie, but it would be nice to have it working since everything else on my car works great, now that I fixed my HVAC temperature control knob pulse generators.

 

I'm glad my OCD issues are in another area.

 

Hey there, longtime Cadillac dealer tech here(I know, don't hate me). Had this problem on several vehicles recently and I know the "working on it" bulletin but here is something to try. (This may or may not have been from tech assist. Can neither confirm nor deny)

I recommend performing these steps.
• Power up the navigation unit
• Accept the warning notification by pressing “OK”
• Press the hard ‘MENU’ button
• On the touch screen push ‘Display’
• On the bottom left corner of the display press and hold for 7 to 10 seconds to reveal the ‘Enter PIN Code’ screen
• Enter the PIN ‘660’
• Then press ‘OK’ to move on to the ‘Screen Diagnostics’ menu
• The ‘Screen Diagnostics’ should now be displayed
• Select ‘Next Page’.
• Select the clock menu and set the time.
• After selecting “Set”, turn the key off and cancel RAP for at least 5 minutes and retest operation.

This has worked several times now but no guarantees-you know the story.
I hope this helps.

Alright, techie. Where is this "hard MENU button" on my 2008 nav unit?

 

It's not a hard key but shows up as a soft key in the left corner of the display when the map is up.
The rest of those steps may work. However I don't believe the 660 code works on the 08 STS.
I'd have to look up the codes again for 08+.

 

Yeah, I've tried that and it didn't work because there is no option to set the clock. But figured the "tech" knew something we didn't when he posted his recommendations that included a "hard key".

 

Try the code 3657, my clock still works and I don’t have time to go poking around right now.
These are the other STS Nav codes I know some depend on model year and reveal different settings.
660
295660
9448

 

Will try this procedure tomorrow. In the meantime, my car's an '06, and I don't have a map dvd anymore (I just use my smartphone like another forum user above does). Is there a PIN for my car? Is there a procedure that works that doesn't depend on the map being displayed?

I wouldn't have a smart phone stuck in my rear end if I had room for a sawmill. I use an old copy of Streets and Trips along with a DeLorme GPS module on a laptop for navigation. After I get there I manually set a waypoint for the next time. After I get across the border into Canada there is POI data for Canada that can be used.

 

I try but I can not find the time !!!!!

 

I have a 2009 STS 3.6. After a few cold days at the end of January in Illinois. -50 with the windchill effect. My STS battery died. Replaced it with a new one and the clock is not working. It wasn’t working for about close to two months. One day miraculously it was working again. I have read it might of been a software issue. But it seems it’s working now on my STS.

 

Is the date correct?

 

FWIW, I drove mine for over ten years before I realized it even displayed a date. In NAV mode mine will flash a date for a couple of seconds if you press on the time display, otherwise you have to have the NAV turned off to see the date.

 

You must be always listening to something. ?

 

I turn up the radio or CDs to drown out the VVT valve clatter.

 

Or is it timing chain/guide noise? Yes, in the V8.

 

Yep, add me to the list. My right side mirror had been going into back up position all by itself, so I though I'd try resetting things. Disconnected the battery, touched pos to neg, let it sit for a while, and reconnected. No clock. Dang it. Called GM. Neither person knew anything. Suggested I take it to a dealer. I gave the second guy the Info Bulletin number and, gee, he had not seen that before. He still said to take it to a dealer. I have a call into my the service department to see if they have any new info.

 

What's this Info Bulletin number you speak off?

 

Call GM back and insist they enter it into their computer and issue you a ticket number. Also, don't waste your time calling the dealer because they can't help you until GM gets off their ass and issues a fix. The more cases they have open, the better chance we have of GM doing the right thing. Calling the dealer does not open a case.

 

After discovering my clock is toast, I got into the diagnostic menu on the nav system. And sure enough, no satellite acquisition. No GPS signal at all. And, as we know, since the clock gets it's time from the GPS, ergo, no clock.

But, here is a question for everyone. How many of you who are experiencing this problem have purchased a nav disc on the black market? I did. I'm wondering if there is any connection between not purchasing a "real" gm disc for $180 and the trouble with the gps/clock? I understand that this issue is wide spread, across several GM lines. However, is it not realistic to think that there are lots of people who didn't want to spend $180 and got a disc off eBay for $15. And might those $15 discs be the problem?

 

The NAV disc has map and POI data only and absolutely nothing to do with system software or GPS operation.

 

Hey Binky,

Yes, I understand that the perceived purpose of the disc is as you state, but it would not be hard to encode something on that disc that talks to the "system" or the gps side of things, so that only GM discs would keep things running correctly. Or is GM not that smart?

 

I have a genuine 2010 GM NAV disc in my STS...alas no clock. Disc source, be it GM or illegitimate copy, is unrelated to the clock problem.

 

curtc,

Well, your confirmation of the clock problem with a real GM disc blows my theory. And I thought I was being really smart. Sure is fun driving around with no clock and seeing myself in the middle of the lake ( according to the GPS).

 

Aside from my clock not working my GPS seems to be OK. It does take a while for the GPS to get signal but it still tracks me fine on the map even when the GPS symbol with the red dash is there.

 

Curtc,

I would bet that you are not getting signals, as indicated by the red dash in the GPS icon. Your map is using stored dead reckoning information. Try driving around in circles a couple of times and then head down the road and see what happens. Go into the nav diagnostic mode and you will likely see that there are no satellites acquired.

 

It was previously discussed that the issue we are all having with no clock also makes it take much longer to lock in the satellite signals it used to take me I would say just a couple minutes now it takes 20 to 30 " of driving to lock in the satellites and it seems I only get 2 now, I assume in the past it was finding more.

 

I'm convinced that the issue is not with the clock at all. It is with the GPS and satellites. For the past three days, my map had me in Washington DC. I live just north of Seattle. No acquisition of satellites at all. No satellites, no clock. It's that simple.

 

Yeah, cuz the nav units in my other three vehicles (with clocks) work just fine. Gotta be the satellites, right?
