Updated Navigation Dvd For A 2005 Yukon Denali (gmt800)?

[JohnEnglish]

I have a 2005 GMC Denali and want to get an updated navigation DVD. However, no one seems to be able to get one for me. I've called several dealers and they've been unable to get it and http://www.gmnavdisc.com (same site as the 1-877-NAV-DISC number) says there's no discs for my vehicle.

 

There are update discs for 2007+ GMT900 Denalis but those won't work in my truck. I've looked around on eBay and found some verion 3.0 discs but the descriptions say that it's the original dics that came with the vehicle and not an update. I've also looked to the manufacturers of the system, Aisin/Zenrin and neither of them have any updates available for it either.

 

Did GM not make updates for the GMT800 trucks or am I just looking in the wrong places?
