Just as the title says, I have a Factory GM navigation disc that was in our 2010 yukon that we dont have anymore I believe this is the most updated version but not completly sure but it is part# 25912408 & DVD rom version 3.10, We bought the yukon with the navigation but took it out as soon as we got it home because we already had a very nice Kenwood navi to put in the yukon that was controlled by garmin, So this disk has never even been loaded. I would like to get 100.00 for it.
