Is there anyway you can enable multimon. I mean when I switch it on it automatically make the second monitor the default monitor and control the system. ONce MULTIMON is enable, video jump to the front screen which I do not want. I dont want to watch dvd in the front. I want to be able to control it use the dvd function while driving and let my rear guess to be able to watch dvd. I do not have a touch screen monitor in the back. I want to be able to view navigation on the front but video in the back. How do I do this and is it even possible.
