Hey, I have just ordered the D3 for my 2006 silverado with bose. I just bought the integration adapter from best buy along with the antenna adapter and install kit but the guy there told me that the hard part about putting this in your self if hooking up the parking break and speed-o-meter and reverse. I think I am going to do the bypass right off the bat so I ain't studing the parking break but what about hooking up the speed-o-meter and reverse? Any advice would be greatly appreciated thanks!
