NJEquinox

Howdy folks. Just bough a new Chevy Equinox and had a question. Does anyone know if there is a device or program out there I can buy that I can use to set the all the windows on the SUV to one touch power down? I can do it on my Audi so I figured Chevy would have the same concept as well. Also, I'm looking to replace that factory stereo with a DVD/NAV system. Has anyone done it so far? If so which model did you go with and how's the look?

Thanks!
