I have approached Denso direct with this, I suggest as many of you, that have this problem (or will have the problem in the future, you will if you disconnect your battery, so get proactive I would say) do the same. Maybe that helps and all we have to loose in the end is time. (Was that a pun too? Not sure.)
How did you approach Denso? It shows on their website (customer services) that they do not deal with anything OEM. Contact the OEM (GM in this case) or your local dealer.

General Motors is aware and has added SAAB to the list of affected vehicles to Denso. The affects 2005-09 9-5 with Navigation (incl 2010 9600's chassis in Europe) SAABs and many GM products across several car lines. This is very early in the process so we wait.


SAAB will be added to this bulletin. We are in the same boat as the Corvette owners.

I went here:

http://www.denso-am.com/about-us/locations/

selected my country and phoned with them. Next I connected with the head office Europe in the Netherlands.

I explained there is no Saab company to talk to and they put me through to a person who in the end even offered to repair the unit for me. Of course this was before we know that it had a software bug.

Next I followed up with an email explaining the situation again.

Time will show the result.

I know people. :cool: Let's just leave it at that.
Do tell! Oh wait, no, don't. I know covert coded wording when I see it lol.

I actually spoke to Denso's Tech Department today, funny convo actually.
The guy thought I was being rude to him when he tried to tell me that the GPS Antennae became unplugged and I told him that nothing inside the car was touched. I only replaced the battery. Then he told me I was being rude and that I wouldn't know since it would have been in the mechanic bay. I then told him I DO know because I replaced it myself in the parking lot where I bought the battery.
I then explained that GPS, turn by turn and location all work fine. It's ONLY the clock that doesn't work anymore. Long story short, he told me to go to a dealer and talk to a service adviser. He had never heard of this issue and said it doesn't make any sense since all GPS timing info shows up when including estimated time of arrival. He was completely perplexed. I was going to say "I told you I wasn't being rude. you were being rude by not letting me finish explaining!" But I left it as is, thanked him for his attempt in helping and ended the call.

Oh! One nice thing was when he asked what vehicle this was affecting (due to possibility of security code needing to be put in) I told him a 2005 Saab 9-5. Right away he goes, "Oh, there is a security protocol on those because they're very high end vehicles. Toyota/Lexus don't bother with that, but Saab's are very high end. Audi, Mercedes and BMW along with Porsche have a similar security protocol in place. There's no hidden menu on these systems though and the radio is working so I'm not sure what else I can do for you"

Hello folks - I have the same problem here in Colchester, UK on my fabulous 08 9-5 Aero Estate Auto with 96,000 miles (barely run in!) - my second Saab & both are by far the best most comfortable, safest & fastest cars I have ever had in over 50 years. Anyway battery replaced 2 weeks ago - only the third one I've had since new - guess what - the clock field is greyed out - how on earth do I force a suitable GPS signal that Mimmi mentioned - I must be getting a valid GPS signal as the Sat Nav works perfectly. Odd thing is that when my battery packed up, I expected the pre-set stations to disappear but they didn't and also I still have the favourites & previous destinations so the memory chip or whatever didn't lose it's contents. Help please as obviously I can't now get expected time of arrival on the Sat Nav either.

You'll have to just live with it. There is no fix yet. And no hidden menu to enter in order to configure the unit directly as you can with other Denso variations. Denso and GM are both aware of the issue (it affects ALL Denso Nav equipped GM vehicles from at least 2005 up to 2010).

My local Saab specialist was getting some grief from a customer about this. The car had been in and battery disconnected for whatever reason. I was able to tell him about this issue and thread and at least he's been able to honestly say it's not his fault!

I have started a thread here about this, and somebody just pointed this one out to me.



The upshot of what I wrote is:

I have been talking to a Saab Shop and they claim that the Denso has a software fault. When you disconnect the Battery it happens, and the screen with the clock is no longer available. Now I have disconnected the battery several times over the years and I never had this happen. I did however disconnect the Battery this time for a small electrical repair, after that the Denso had the problem.

And:

OK I discovered more. Via the Saab Club NL I found the following info. It is, apparently, a known problem and seems to be a software fault.

If you disconnect the Battery it happens. You can no longer set the clock and there is a stripe through the GPS symbol. However the Navigation still works so there seems to be a GPS signal.

It is a software bug in all Denso units from 2005 till 2010. US Cadillac’s apparently have it too and apparently the Corvette C6 has it too. According to the poster is GM working on it.

If I find out more, I post.

Still, I be interested to hear if anybody else has the problem or has a solution or other information.


As to disconnecting the battery I suspect it is true. However I also like to say that I have disconnected mine many times over the years without any problem it just happened after this last disconnect.
I got the same problem after picking the car up from the tech. service. The mechanic said he did not disconnected the battery at all, as the reparation was to change the oil vapor recycler.

It's BACK!!!

On my home from work tonight on a rural hwy with no lighting. Everything was normal, my xenon headlights beaming down the road illuminating everything in front of me when all of a sudden out of no where ALL my dash lights, gauges and headlights just shut off. No loss of engine power though. a split second later, everything came back on. Now, I don't know why I thought of it behaving like a reset, but I decided to check the clock on the NAV and guess what?! It's back! I just have to figure out how to change the date again lol.

Imagine all of sudden a complete loss of lighting


And the Clock adjustment is enabled again!

It's very interesting information. I am also glad you could get this functionality back again.
Not sure if I could reproduce that kinda "reset" by .... puzzling: disconnecting the battery would not switch the headlights off...

Anyway, Thank you very much for posting. It gives some hope.

Just as an update. So, Although I can manually adjust the hours and minutes, actually does not mean the clock is working. The date is way off (Jan 01 2000). GM is very aware of this and there is a fix for Denso systems released on the 11/11/2019 (provided by the Corvette forum who share our same Nav unit). I haven't tried the official fix yet. But here's the GM Service Bulletin regarding this issue. You can take the car to a GM dealer (it's supposed to be a free fix from what I've read) or you can try the Denso fix provided by the Corvette forum.
NOTE This is a direct download link to the file.
https://tis2web.akamai.gm.com/radio/corvette_gps_my_05_10_fix.zip

1. Download the zip file.
2. Extract the KWI file.
3.Burn the KWI file to a CD-R a DVD disc will not work.
4.Start your car (Remove NAV Disc/Do not press NAV button).
5.Put the CD-R in the map disc slot.
6.The update will start automatically.
7.Reinstall your Nav disc and you should be good to go.

Technically, since this is just a clock programming file, it should work without issue on our Saabs as they share the same Denso unit as the Corvette. No additional changes are made to the Nav unit (as in no extra features, no new maps, just the file to fix the date and time).

I am not responsible for any of the unforeseen issues that may come about by doing this yourself including the worst case situation of bricking the Nav unit.
If you are not comfortable with the risk of doing this yourself, then I strongly suggest and urge you to go to a GM dealer instead.


Take note of this document as well when visiting the GM dealer so you can provide them with the Service Bulletin number.

Mine went out in March after disconnecting the battery and came back last month in the same way that Nocturne described above. I don't really care that the date is wrong or that the clock has to be manually adjusted so I'll just leave it alone.

GM did not release software for SAAB because Denso could not find our source code. The software you have presented is not for our cars and could do more harm then good. It has not been tested in any SAAB to my knowledge. The fact you post this without even trying it is the worst part.

Maybe you missed the part where I state the risks and suggest going to the GM dealer plus mention where the fix came from. And how could Denso not find the source code seeing as its their unit? It's coding for the gps satelite clock regarding the interpretation of the binary for weeks after 1024. Should be the same across the board for all vehicles in the list provided in my post. They all share the same Nav unit and the clock issue affected every one of them. But, okay, I'm the bad guy because I updated this post for those interested.
I'll go to my GM dealer and reach out to Denso (again) and see what they both say regarding this bulletin and the sharing of the Nav units across the stated GM vehicles.
