I must my radio unit apart, I am installing a rear view camera. I notice that there is a square blue port that has nothing plug into. What is that for? Is that for a new feature that can be added to the car?

According to this thread, the blue port is for Aux Audio. Scroll down to the last picture of the first post.

The aux video and audio ports are for the multimedia interface that would have terminated in the glove box. You could probably just buy the parts and wire it up yourself while you're doing the reverse cam. You'd only have aux audio since the video feed will be for the reverse cam.
