Just bought myself an RX-8 (2004) and day one I somehow manage to crack the defroster buttons, no idea how, but anyone have an idea of how much this would cost to get repaired by a dealership? The buttons themselves are obviously going to cost almost nothing, but I don't just expect them to pop off and be replaced - Will the whole head unit need removing?

Is this something I would be able to do myself too? I haven't been able to find the specific parts that are damaged online, only whole head units.

Cheers.
