Plus the two vertical lines are for the antenna. The owners manual says that if the glass gets scratched, then the radio reception would loose quality. But that doesn't quite explain why it only happens when the defrost is on.
yeah i had the smae problem, my xm radio puts out a very weak fm signal and the rear defroster really doesnt help. i beleive i did see a recall on that on the nhsta website.

When you activate the electric defroster it sets up an electric field across the wire grid lines and the electromagnetic wave propagation interferes with the ability of the antenna to receive radio frequencies.
