The other thing is installation. My guy who works at circuit city is going to install if for me on the side for $50, but i was told that the brain would not be covered if it was not professionally installed by a DEI certified something. However, I thought about it, and it would cost me another $250 to replace it with installation. Where as if I went to get it installed, it would cost me roughly $4-500. So I am going to take my chances i think and have my boy install it. Do you guys agree???
