Hey all, I know this topic has been around the forum in the past. I just thought I'd let everybody know that I just installed the DIC buttons in my 09 Silverado. It was extremely easy, and took about 20 minutes total. These buttons are a real convenience with information like distance til empty, tire pressure, and many other features. If you don't have the DIC buttonsI highly recommend you spend the $90 and order one. You can easily install it yourself, no wireing needed! I'll be more than happy to answer questions!
