Wrong ,the newest disc is the 6.0 verison and the part number is: 20861474 so your disc WILL NOT WORK in the 05 thru 11 STS. The only disc's that will work are:
V 1.0 10381281
V 2.0 15794606
V 3.0 15924195
V 4.0 25852830
V 5.0 25976806
and the one listed above.
They can be had on ebay at a lower price than the GMNAVDISC site. Hope that helps.
If you go with an ebay offering, know that newer levels split POI's between east & west. The right disk may be a good deal for you, but the set contains two.
Why two discs now? All of the information use to be on one disc.
