The original radio would have known when it could run via the GMLAN through the green wire I believe. For your aftermarket radio, you need to provide an accessory power to the red wire. This is something that comes on when the key is in the ACC or ON positions. I can't remember which fuse I tapped into but I used a Bussmann Fuse Tap and ran the additional circuit up to the red wire.
