i need some help. i just bought a truck and want to install two vga touchscreens in my sunvisors. i want to be able to use either moniter, for example if the passenger wants to select a song on my car computer i want to be able to use the passenger moniter, or vise versa. i want both moniters to view the same thing and be able to make a selection on either moniter. hope that makes sense any help would be appreciated. thank u in advance.
