Chris, the manual lists all of the options available for the radio, and D-Star isn't one of them.
I can't speak for your neck of the woods, but on this side of the pond, D-Star repeaters are few and far between except in some of the major cities. Even then, they're scarce. Hopefully, that will change in the next couple of years. What will really spur things on, is to have Icom just include the option in their D-Star-ready transceivers. In the mean time, I wouldn't sweat about not having it.
