No power to radio and interior lights

Evening all, and Happy St. Pat's Day.
On Friday, all was well with my truck, mostly anyway. On Sunday, I had no power to the radio or interior lights. All else electrical appears OK. I checked the 10 amp fuse on the interior fuse bus, and the under the hood fuse box as well. However, the diagram indicates nothing under the hood that powers the radio. I haven't ruled out both a bad fuse and a faulty spare, so will plug in a new one tomorrow, but if that isn't the answer, any ideas on where I go next.
I miss my XM radio!

Check the IOD fuse in the in-cab fuse box. I don't remember the number, it has a plastic cover on it.

Greg, IOD was the problem. Why the heck is it called IOD? there's a separate fuse labeled "radio" but no clue that IOD supplies radio, interior cab lights, side mirror adjustments. Thanks for heads up
