Hey everyone, just got a 2005 Silverado 1500 I have two questions. First, how do you add HomeLink (Garage Door Opener) besides getting the overhead panel? Second, I have DIC controls and someone hacked in a aftermarket double DIN and the audio controls don’t work. I plan on changing the radio out with something with Apple CarPlay from Crutchfeild. Where’s the factory microphone when you press the button on the steering wheel?

Thank you for your time!
