Well, I looked and didn't see any posts about moding the overhead compartment... i believe its designed to be a sunglasses holder? But i was lookin at mine the other day, and wondering if i could do anything with it since my Nike sunglasses don't fit into it. I think it owuld be a good place to put a navigation system screen, but you'd probably have to mve the rear view mirror down about 1" so its not blocked ... anyway, i was just curious if anyone did anything unique with the compartment?
