Good used auto dim GM rear view truck mirror with compass, outside temp, and airbag on/off indicator.  This optional mirror came in some 2003-2006 Silverado, Sierra, Tahoe, Suburban, Yukon, and Avalanche.

No OnStar buttons on this mirror.

These will work in 2003-2009  Silverado, Sierra, Tahoe, Suburban, Yukon, Escalade, etc as well if you don't need onstar or just want to get rid of the useless onstar buttons.  Will not fit older trucks with single row plug.
