The IR signal from the dash can be picked up from the ICC connector. I simply wired this up to a point inside the DVD/STB unit where I had cut the units own IR signal and replaced it with the car's one. Inside the Skymaster, there is a cable coming from the front panel (which has the display, IR and buttons) to the main board. Where this joins the main board, you can see the "IR" signal labelled. If you want I can probably take pictures of the auto switching cct and the IR patching inside the unit.
