I am trying to figure out a way of installing a carPC into my 06 GS300. I have heard of video converters that will convert the signal to be able to be displayed on the OEM screen and also be able to use the touch screen, of course this would involve a switch that would change the video source and touch controls. Unfortunately my GS300 is a NON-NAV so I would like to know if Lexus uses the same screens for both. If not would I be able to install a NAV screen in my non NAV GS? any input appreciated,
