I have the older version already set up with wiring harness for the radio in 2010 Sport Trac. You can do a lot of things with this. You can set up a back up camera that shows on the screed of the radio, you can make it so the DVD plays while you are driving. I used that when my kid was little so he could watch a movie while on long drives. It did plenty of things that I didnt even use but maybe you would have use for. Basically you unplug the radio and plug it into this and plug this into the radio. Its Plug and Play. You would probably have to contact them for instructions on use and set up, unless I still have it and can find it.
