Another Nav diagnostic code

AND: Don't forget the $199/year for the right to pay those exorbanant prices.

You'll find that most let it drop after the 1st freeby year.

In some states you can now add your Onstar phone to your verizon account for $10/month and you share minutes. OF course, you have to have a digital onstar system, and most cars don't. And, $10, come on that sucks!

PLEASE move on to the Mac, Linux, or other such "I'm important--work for the biggest computer whatever in the world, I can't get over MS forums". It's as if you were waiting for someone to mention MS so you could fight with them. The example was good, if there was competition in this market the prices would be lower...simple as that.

Anyhow you along with a million other developers that Microsoft employs.. should know the kind of gook u guys put in your software. If I find a browser that is hack proof at least today.. hey THAT IS GOOD NEWS for me.. and if that threatens MSFTs existence, hallelujah!!!

I saw that you stopped at the cookies and did not talk about the other myriad vulnerabilities that using MSFT garbage hurts the common user -

Check this out - go to your PC and do a "Windows update" .. and go on doing it till you get "No other updates available" .... come back here and post something valid - after about 100 years!!

Dude, I do not want to pick a fight with you, but please do not sit on a high horse and think that just because you work for MSFT its worth defending all its actions...

I hate to bump this so late in the game, but I'm hoping Sonar Tech will see this or someone can contact him(I don't have enough history here to post private messages).

I think everyone with a GM is trying to figure out the codes on this thing. I know we are over at Corvetteforum, which is how I ended up here.

Our navigation systems are little different than yours, but there is a secret keypad that can be accessed from several different locations -- and it takes up to six numbers, so brute forcing it isn't really an option.

However, here's the interesting thing. A couple of months back, we got an upgrade to our Navigation systems. It came on two CDs and loaded itself onto the firmware of the navigation unit itself. It fixed a few bugs, and most notably gave us all mp3 capability. The discs are 10MB each, and can be grabbed here: http://forums.corvetteforum.com/show...&postcount=152

Why is this interesting? Because, whatever was on these discs rewrote the operating system for the navigation unit in an un-trivial way. Personally, I've been trying to decrypt exactly how it works in the hopes of writing some patch code that might update some strategic sections -- like the "nag screen" for instance. But, I'm getting stumped. I don't really have the nessessary equipment or the right kind of software background.

Sonar Tech, where are you?

[HITMONEY]

I wonder if that Corvette NAV update CD would work on our Denso's???

I for one would LOVE mp3 capability.

[eintier]

Those updates will likely NOT work for your unit. The units are actually pretty different, though they run similar software written by the same company. Kind of like asking if a wheel from one of our Corvettes will bolt to your Cadillac. Maybe, maybe not, and even if it does, it might have unintended consequences.

At any rate, it's been rather fruitful over at Corvetteforums. We've found three new codes that appear to be specific to our navigation system only.

660 brings up a diag menu that does not have an exit function.
295660 opens a menu so you can actually see the information from the satellites you're communicating with.
9448 opens a menu with two other menus -- Software Update and Auto Demo

SonarTech's suspicions about what the LOADING.KWI does was literally spot-on. It is a program for uploading new code into the navigation unit and appears to be complete code rather than a patch. FIGDAF knew enough to lead us down the wrong paths due to his assumptions about his gaps in knowledge. Much of this is detailed in our thread.

Of particular note, we managed to pull those numbers from our LOADING.KWI file by looking for 3+ digit number strings in the file -- both in plaintext and binary format. The ones that work were simply encoded in plaintext.

We've also developed a Java tool for decrypting the KIWI format, so we can read that and extract binaries from it now as well -- which we've done. We're currently working on building decompilers to take it apart further. Hopefully there are more secrets and codes we haven't found yet.

Thought I would share, the more minds we get thinking about this, the closer we get to solutions. I'd also like to see any LOADING.KWI files anyone has, Denso likes to reuse codes, the more working codes we can find across all lines, the more likely it is we'll find more that work for ours.

Keep us informed.

Only codes I know of on our units that I know of is the 1791 DVD code and I think its 1971 that brings up a diagnostic interface. I bricked my NAV messing around in there, thank god I managed to get it warrantied. I don't mess with that code too much anymore. LOL I basicly reformated the thing, and there is no where to get the firmware or software. I couldn't even shut it off as the buttons lost all funtionality... it was bricked real good.

That sux! How did u brick it? Did u take it apart or enter a code that messed it up? And what code was it?

On my original '04 Nav, I've tried all combinations of the above, and got nothing. Not "bricked" either!

I opened a diagonistic screen, I can't remember the code, but I found it here. It had some different options, I was foolish enough to try some of the different options and tests. One of them basicly reformated the NAV, erasing the entire operating system. I was like, "Uh Oh!"

I couldn't even shut the thing off, it was always asking for a system CD. I imagine this is the only way to reload the operating system. I called my friend who is a Cadillac Tech, he had no idea of any master CD.

Through some very good friends, I was able to get the thing warrantied... thank god. So I ended up with a brand new NAV, WITH the most current NAV disk. But, the whole experinece wasn't nearly worth it.

I have sworn off messing with the codes, and just keep with the 1791 to watch DVD's.

Hit - I also have a Grand Prix-GXP which has the same basic NAV unit as the 'Vette. Which button sequence did you use to get to the diagnostic screen on that unit? TIA

I tried both of those codes 295660, 9448 and nothing. I am wondering if they do a firmware upgrade on some of the units bought off of ebay. I did talk to someone from Schram Auto Parts and they said that there units (were I got mine) were factory reconditioned. Now I just had a though. What if we could find out what company reconditions the units? Maybe they have some info? Any thoughts?

Not to further confuse an already tangled issue... I have an '04 DTS. None of the codes provided over the past 15 pages have any affect on my nav system. When I attempt the various codes provided the system dumps me back out to a regular map/navigation screen. However, strangely enough, 1791 doesn't. When entered it leaves me at the code entry screen as if I'd never entered a code at all. It would appear I have yet another variation or version.

1791>Enter>Return should put you back to the blue Cadillac Crest splash screen. If so, the code is entered and functional.

I will also try and find the code I used to get to the diagnostic screen.

[Twain427]

I understand, thus far. However, what is the benefit in this case? I press return and I dumped out at the Cadillac wreath & crest splash screen. Where to from there? The radio still functions as normal. However, maybe I'm misunderstanding the function of the code. By entering the code and being returned to the spalsh screen; the system will now allow me to play a DVD while in drive? (which is what I'm ultimately attempting to do) I guess I was assuming by entering the code I'd be directed to a diagnostic menu of some type, from which I could override the saftey function. Would you kindly clarify?
