I am installing an aftermarket DVD screen to my 2007 entourage. I have installed everything, including all the wiring and am now ready to install the dvd screen. I have a base model entourage and am not planning on taking the ceiling down. is there anything in the ceiling that I should be concerned about forward of the center dome light, other than the domelight wiring? Is there anything to mount the mounting plate to in the ceiling? Any help would be appreciated.
