Do you have the book on upgrading a 2003 avalanche  to lux amp with navigation  I am not installing  6 disc cd changer for now. I have a unlocked luck nav unit and a used lux amp.   I have installed  a wire from cluster to  radio   I do not have onstar or xm radio from factory so no vci came in truck. I had to get a harness for back of radio because there is only 1 harness to radio from the factory
