Hey guys. I just bought a 2012 Laramie and want to install monitors in the headrest. I wanted to know if the factory stereo (nav/dvd 430 or 740?) has a video output jack to run to the monitors? I have read about lockpic? that taps into the wiring harness, to have rear camera at all times, dvd at all times etc. I am not worried about watching tv while I drive, but want to hook up some monitors so my kids can watch on road trips! Any advice, help is appreciated!
