Actually, I realized today that I ordered the wrong part. I just order the control panel (volume control, menu button, etc). The amplifier I'm learning is part of the CD player box. I've unplugged that, and everything went quiet. Called the dealer, and they say they have a new one coming for me for $255+tax. The found the part by looking up the part number on my old player. But, they needed my vin to order it--I wonder if it will be programmed and ready to plug and play. Also, they need my old one as a core.
