I just bought a 2012 Georgetown.... I wanted to mount a satellite on the roof however.... Don't see anything on the roof that would tell me that it's prewired unfortunately.
What I do see is in the right passenger upper cabinet where the DVD play is I see a winegard electrical plate that has a coaxial plate and 12volt conductor. It also has an on off button and it appears that it has power hooked up to it.
My question is.... Is this a prewired set up for a portable satellite set up ?
I have included a couple pictures.
