I have been told that when replacing the factory Bose unit that just about everything needs to be replaced (Wires, head unit, speakers). How true is this and is there a head unit that can just go in and replace the factory Bose unit?

At Crutchfield when I look up head units for the Camaro, this is listed in the installation section.

Your vehicle is equipped with an upgraded sound system. We recommend that you purchase an adapter to eliminate extensive rewiring when you install your new stereo. Without this adapter, you might have to replace your entire factory sound system, including the speakers.
