Good used rearview mirror with auto dimming, compass, temp, and onstar buttons.  There is NO airbag on/off light on this mirror.  This is a newer style mirror that does not have the external compass sensor.  Fits many GM trucks and SUVs from 2003-2009 with similar mirror.  Will work in 2003-2006 Silverado, Sierra, Tahoe, Yukon and Suburban if you want a mirror with no air bag on/off light.  This mirror came factory in 2007-2009.

Temperature will only work if your vehicle already has this option IN THE MIRROR and the sensor is working properly.  If the temp is in the dash display and not the mirror, the mirror will not show the temp and will read OC.
