hey all, I'm brand new as you can see. I'm considering buying a D3 and I want to know if anyone has installed this in a 2nd Gen (98-05) GS without factory nav. Any experiences, pics, whatever are helpful. Specifically I want to know if the factory changer and factory subwoofer can be utilized in any way, and how it looks installed/how easy it is to install or how expensive it is to have it installed.
