Anyone know what kind of connectors are on the back of the 2002 XE model radio? Anyone know how hard it is to take the radio out?

My Xterra came with a loose cable that I suspect is for a CD changer. It has 4 wires: white, yellow, green and brown. It has a flat plug on one end, and a square plug on the other. Anyone familiar with this cable and know what it is for?

Some of the discussions in the linked forums are very technical, and involve more than I am willing to do. In my experience, every time I mess with a car, I make it a little less nice. I put a screw back incorrectly, or I scratch something (stupid me). I want to make sure that my taste for static free music does not ruin the center console. Anyone know of a good installation shop in LA that can do this type of work? The dealer could not do it, or declined to do it.
