Just updated my Gen 2 Touch 9 to the version 4 released recently. It primarily updates the menus to look like Gen 3. I like them a lot better than the Gen 2 menus but now have to learn my way around them. I just was getting comfortable with the ones that came on it. The new version is more user friendly. I believe there are several other new updates also. I just updated a friends brand new Elite 7 the other day. Just an FYI in case you haven't updated recently.
