Car dvd

Hi all,

I'm a newbie here and I just purchased my 2011 Corolla less than a week ago. I'm doing basic mods to it (aesthetically only) because its my long commuter so I don't want to sacrifice the MPG's. I came across a DVD/Nav system on http://www.justcardvd.com/

has anyone had experience with this system? It seems neat with DVD player, navigation and back up camera. It also retains the factory functions like BT and steering wheel controls. Please advise, thanks!http://www.justcardvd.com/
