I have an Avic-D3 on the way and want to install an additional monitor in my passenger sun visor at the same time. Does any one know of a good write up on installing a visor monitor? I have an 06 F250 that has the mirror/light in the visor approx. 7 5/8" long. I think the Power Acoustik PT-727MSV 7" monior will fit ok... I just don't know how much work it is....
