Default Adding Nav to a 2007 TrailBlazer

I've got a new '07 TrailBlazer with Bose.. I'd like to add a navigation system to it. Reading up a bit on the other posts, I *think* that p/n 15940102 is correct; can anyone confirm? I think p/n 15229287 is the older unit that can't do DVD while sitting still, but am not sure.

Also, how hard is the install on this? I understand I'll need the head unit, navigation dvd, and the antenna.. anything else? Does this require a run to the dealership for programming?

Thanks!
