Navigation Secret Keypad

[Highland Ranger]

silly question - did anyone try 001791? Mixed reviews on the coastaltech device leave me uncomfortable.

waiting on my ltz . . . . . hopefully I'll be trying it myself soon.

So I'm officially done with this thread, the main reason I wanted to bypass all of the security features was because of the damn OK screen coming up every time I use the car. I just got my nav replaced (cd drive wouldn't load) and they gave me a brand new one, and it hasn't made me hit ok yet (although it probably will every 50 uses or so).

That said, I did find something very interesting before I had to get it replaced (they had nothing to do with each other, it was a mechanical problem and chewed the cd up, literally). For those of you that can use the 9448 code, theres a menu called "Debug" and I think THINK that you would be able to manually change values to potentially override/bypass any triggers for security features. I didn't have a chance to try it out but it the results could be very good.

cool..will try it out. I think there is a software upgrade in your new unit. I found out that many of the dealer techs/mechanics don't know a whole lot. They receive updates every now and then from the factory about changes or "how to fix xxxx".

thanks

i noticed it says alldata on there?? thats a program that helps techs fix vehicles, its like a super library for most vehicles ever made. how did u get that on there

 

[thetahoe]

I read this and tried it on my hoe. I got frustrated with 660, it eventually left the menu but my car still wouldn't shut off!
Mom won't let me try it on her ESV, she's so paranoid it'll mess up [she hates going to the dealer].
BUT this is an interesting find, I hope you guys come up with solutions to the annoyances of these navigation systems...like that stupid caution screen.

(note. some info didn't cut and paste, so if someone can tell me how to attach a file, i will do that)

look at below TSB...it talks about new software update to unlock certain features when driving. Mine is early 2007 ESV and I am waiting for my free upgrade disk to see if if updates radio with new features. Right now my radio does not have updated software. Any way take a look and hope it helps.

also here is a tsb (technical service bulletin) that may help.

Condition

Some customers may comment of any of the following conditions:
• The Navigation Radio display intermittently goes blank or turns black/off after switching video sources. This most commonly occurs when the shift lever is transitioned from PARK to REVERSE to DRIVE (or vice versa). Other possibilities include switching to DVD movie or Rear AUX (if equipped).
• The Navigation Radio screen may intermittently freeze, lock up or display "MAP DVD Read Error" messages.
• Some features may not be accessible while driving. This includes scrolling lists, address book and navigation related entries (i.e. entering a destination).
• The Navigation Radio, upon startup, will continue to display the vehicle logo repeatedly. This condition occurs when the vehicle language has been changed, using the Driver Information Center (DIC), in the previous ignition cycle.

Cause

These conditions may be caused by software anomalies.

go get a photobucket account and upload the pictures to your account, then using photobukcet copy the links that start with into the post they would be very helpful

i tried holding menu and seek forward and all i get is a beep...but it is interesting in that it confirms that the map discs hold the new versions of the software which i still think is STDVCE.kwi

i googled stdvce.kwi and found this...someone with more computer knowledge might know what this guy was trying to do (translated from japanese [url]http://translate.google.com/translate?hl=en&sl=ja&u=http://mimori.org/~h/diary/d200205.html&sa=X&oi=translate&resnum=1&ct=result&prev=/search%3Fq%3Dstdvce.kwi%26start%3D10%26hl%3Den%26safe%3Doff%26client%3Dfirefox-a%26rls%3Dorg.mozilla:en-US:official%26hs%3DIvT%26sa%3DN0[/url]

This is great! I have been monitoring many sites for progress on this issue and it seemed it was getting to a dead end. Now that the information is flowing again, it seems that there is a good chance that we could unlock the full potential of something we paid for.

By the way, I have tried the secret screen trick and it worked on my Yukon Denali '08 (Just the 295660 and the 660).
The second part regarding the NAVI software version, I could not get the version of my NAVI software by following the above illustrated method. Can anyone confirm that this works on Denali '08?

Keep up the good work.

 

[jaycough]

i got it to work on escalade which is way different, and also on a tahoe..both 2007. I am going to dealer on moday and will software to list. My vehicle is an escalade,,will let everyone know what it does for me.

I if I remember correctly... new NAV disc hit the street in Oct of each year.

 

[slant911]

Yep my new 2009 NAV disk has been on backorder for a month. SOmeday it will show up.

 

[jaycough]

heard from guy who got new disc, that radio features did not change with new disc. I am going to my dealer on monday to get it updated and other little things. I will update, but mine is an escalade

 

[ibobby]

I tried to hit MENU and SEEK but had no luck getting it to work. Seems I could not hit the buttons at the same time.

 

[thetahoe]

In both my Tahoe and Mom's ESV, no luck with hitting "MENU" and "SEEK" simultaneously. I don't get it, maybe I'm missing something.

 

[khalilio]

I tried to hit MENU and SEEK but had no luck getting it to work. Seems I could not hit the buttons at the same time.

I'm not sure this actually works on Yukon or Yukon Denali, I've tried the (Menu+Seek Up) buttons on both cars but no joy! I'll keep trying for its worth it.

ya. I only tried it because of the instructions and photo on the link above. They showed a pic of what looks exactly like the radio in the Denali.
