boberto00 what wire are you talking about in the drivers pillar. I'm trying to help my brother install his AVIC D3 in a 2006 Silvarado (no onstar) and can't figure out the Illumination. Mine in my 06 Civic works fine but I can't remember (which I'm sure its different) what I done. He is also going to connect a back up camera to it. Don't it need the reverse wire instead? Thanks!
