Cobalts come with Bose?
They SHOULD come with pioneer system with the factory subwoofer in the trunk on most of the LTZ and stanard on SS models
and $300? screw that!
Metra GM OnStar® Interface General Motors OnStar® data bus interface (Model GMOS-LAN-04) Retains OnStar, factory door chime, and factory amplifier at Crutchfield.com
^^^Thats what you need if you want to keep your onstar and door chimes.^^^
Or you can just wire them yourself but you'll lose the onstar and door chimes...
i think i still have the wiring layout for our '07 radios.
