On my Pioneer av system I have made the in dash video function as a great color rear view camera. It is especially bothersome that whenever it is one there is a message across the scree top that says "Caution the image may be reversed" I want to erase, turn off, or remove the message. Has anyone found a way to remove these graphic messages? I know it not a Barth issue but nothing suggests there is a way to turn of messages built into a in dash video screen.
