Sort of related topic, does anyone have access to or has anyone seen a diagram for the installation of a satellite antennae in the IS? For my last car (a Scion tC) I was able to find a step by step diagram of installing an XM antennae, which was basically the same thing for Sirius. What I want to know is which seats, panels, etc need to be removed to get from the truck lid to the dash board. In addition, has anyone seen instructions to take apart the dash around the radio and the center counsel? I have started to tug on a few pieces, but I’m afraid I might break something…any help would be appreciated.
