Help Crack NAV Screen Diag PIN Code
Keep up the good work.

Seriously, I sent the stuff, and by all means pass it on to SonarTech or whoever's interested; the more input the better.
Right now I'm dealing with information overload - looks like Denso has an OS of sorts for the Super-H type CPUs, and has done a joint venture with Toshiba and Sony to develop an OS for the Toshi x49 SOC, which uses MIPS architecture. And of course VxWorks is a possiblity, but that usally uses ELF formats so I'm betting on the proprietary OS and a Super-H. Most likely something related to TRON, a pretty common Japanese RTOS. Many articles about TRON, but I haven't found a lot of documentation so far.
I do find a fair amount of stuff labelled "callback" in the code, which implys some sort of windowing system most likely derived from X-Windows, and path strings using POSIX-style notation so I think we can let out Microsoft Windows CE.

On the reverse engineering side, would it be possible to get the code/disc for one of the similar units where you know the PIN (1791 for example), see if you can find the 1791 in that code, and then try to use that information to get an idea where the PIN might be in ours?

In this world, I've been sending out emails and posting here asking ANYONE who might have access to these codes to send them to me and I don't know one person who works at GM in any capacity.
In all that time, no one's sent me one code despite the fact that I'm promising anonyminity and will take full responsibility for distributing the codes. It wouldn't be hard; disposable, untrackable email addresses are easy to find.
With no contacts at GM and no serious ties to the automotive industry, the social engineering route is pretty much a locked door. Finding out who I need to talk to and lying my way into obtaining the codes from them feels like an even more futile effort than this -- and I can't really talk on the phone for extended periods during the times when those people would normally be available. I do a lot of this while I'm stuck in meetings and don't have anything to contribute.
So, I'm doing the best I can -- picking at the KIWI files and hoping for the best. Why don't you try calling them and getting the codes?
Also, if you read the thread and look at the linked pages, you'll see where we've managed to find two seperate keypad entry screens, and someone has actually seen an engineer at the Corvette factory enter a pin and access a hidden menu -- that's how we knew where to look for the hidden button in the first place. However, I know this discussion takes place over about 15 pages on three different threads, so I understand how you'd miss something.
Perhaps if I'm feeling bored on the plane tonight, I'll type up a "master document" of all that we currently know about the navigation unit.

Please, send me the files and docs, I sent you a PM with my email. I don't code much Java today, but it paid my bills for about seven years.
We found some more numbers in the binary code today:
Also, I've been passing emails back and forth with SonarTech, who did most of the heavy lifting over at CadillacForums. I think it might be worthwhile to run this KIWI analyser on the LOADING.KWI file that's on his disc as well. I'm wondering if all LOADING.KWI files are essentially the same, or if they've changed over time or even from car to car. Since we only have this one, any others we can source would be welcome.

Anyone have a pin for this?

This may have been posted already, but here goes. I removed the NAV DVD and put in a movie DVD and an error comes up. The error says something like this insert a nav DVD. At the top of the screen there is the word "Caution" in yellow. Press the middle of the word caution and the number pad screen shows up. I tried a few of the codes already posted, but nothing happened.
9448 and 295660
9448 has 2 additional menus: Software Update and Auto Demo
I did not see anyplace to disable the "agree" button or allow the unit to play DVD's.
Thanks much to all who have contributed to this so far!!

Where is everybody ?!?! I am going nuts here
It is too bad though the really important stuff isn't back there like turning off the i agree button or enabling the destination input while moving... rats...
I have been poking around in the loading.kwi file with a hex editor and I see that the following codes are close together in plain text in the file, 660, 295660, 9448, and 1791. Interesting that the 1791 code is in there, this is the one that the Cadillac folks say allows them to play dvd's, but so far ours won't do it.
The 660 code works for me too, but the diag menu under 660 doesn't have an exit button, you have to cut power to get out of it. At first I thought it made the I agree page not show up, but I found out that after you turn accessory mode off in the car, if you turn it back on within a few seconds the I agree page doesn't come up, you have to wait a while, same with the corvette banner page.

And yes, someone has to throw a party or something. Where is ein Tier and Buffy ? they should be crowned
So what we know so far is that three codes work: 660, 9448, and 295660 and they were found in the loading.kwi that is available on the FIRMWARE UPDATE CD
please correct me if I am wrong

Sorry.... I'm just really excited. I'm sitting in the airport in Vegas and grinning like a big stupid idiot. Now, if I can just get back to Austin... I'm on standby.
I gotta play!

But there are a bunch of codes and gobblegook that Ein Tier may find interesting.
Funny that we are on the verge of cracking this, and I am taking my Xterra on a an off roading trip to Moab, Utah for a week with my friends...

Buffy's also working on decompilers. If we can get those to work, we may uncover even more functionality -- including stuff that might be "not so obvious".

While I'm the one who posted those codes, and I technically found them, my work wouldn't have been possible without the help of literally dozens of people all over the net --it is impossible for me to remember everyone. I'm sure that as we move forward (I know I'm not done!) there will be even more people to thank.

Wow, I had given this topic up for dead, I love this forum!
