There a few manufactures that make the wood effect facia. Kenwood and Pioneer from the top of my head. Kenwood excelon series have an attachable faceplate face that can be inter changed to the wood replica. Kenwood calls them "cosmetic panels" . Do check Crutchfield.com as suggested but I am not sure if they offer the panels with their units. You might have to contact the headunits company directly. Hope this helps some.
