I got a dvd player with a built-in tv tuner. I'm trying to get it hooked up to a sun visor monitor. I wanted to use my original sun visor so I bought a 7" wide screen monitor for the sun visor but the guy said it's to big. I took it back and got a Universal Sun Visor with a 7" wide screen monitor inside but that is to long. Now am stressed. Has anyone put a monitor in there C-Class visor if so what size and model. I really don't want to settle for 5" monitors. If you have photos please post.

Thanks
