Although it says 2006-2009 It still works for the 2005 also which I have. Allowed me to install a aftermarket nav with retaining onstar and all chimes etc perfectly. Not many products out there for the Sts and this one came in handy. No complaints except for the size its hard to find room behind the STS dash to fit it.
