Dom is a supporting vendor at our sister site, 300cforums.com, and has done quite a few systems for members there with good feedback.

So, Rubicon, I'm assuming the entire unit has to be removed and sent in for them to install this modulator. And if we all ready have the VES w/ the DVD player in the back will we still need an additional video unit. Did I read that right? :o
