My nav DVD is the original that came with the car and is dated 2004. I was trying to find out if a newer version of the DVD would work with older units in the Saab 9-5. It appears the nav unit hasn't changed from MY 2005 through 2009 so my best guess was a newer disk would work fine.
https://www.gmnavdisc.com/ only lists disks for 2007 - 2009 models. It's interesting the DVDs for the 9-5 are also compatible with other GM models.(Corvette/Grand Prix/9-5/STS Navigation Disc). Those come up on eBay quite often and are bit less expensive than ordering new from GM.
I am using the 2009 DVD (25976806) and it works fine. They actually went from 1 to 2 disks (East and West) because they couldn't fit all data on 1 DVD anymore. They are dual-layer DVD's and there is about 8GB on each disk.
I also found a way of making a backup copy on a DVD-R DL so I am using that in the car and keep the original disk at home. The 2005 disk was already scratched up a bit so I can always burn a new copy if needed.
I also got my hands on a 2008 Western Europe map DVD and that one works fine as well. I don't really have a need for it but it is interesting to see Trollhattan on the screen with the Saab Bil museum and Saab ANA as points-of-interests. Unfortunately, it couldn't provide any guidance to drive there from Michigan.
