What is the black "fin" on top of the 07' Chevy Silverado's? I have seen them on other luxury vehicles, but I only like the ones on the new Silverados. It's not a "shark fin" like what the BMW's have, but it's similar. I want to know what is it used for, and can I get one to use for AM/FM radio only on my 06' Silverado? I don't like my current black antenna stick, and would much rather have the cool "fin" antenna.
