About 6 months age my husband bought me a set of Tv head rest. We put them in and was going to hook them up to the head unit. When we found out we was missing important parts. I went to our local radio shop and ordered the cord.. He was zero help. After trying to get them for two month we gave up. Mean while my dvd player went bad. But I have saved up and bought me a even nicer head unit. My husband made up the wire ends himself and installed the radio and got the headrest monitors up and going. So the kids will have movies and games to play on long trips.
