Convert Visualogix DIN Screens to RCA

I've got 2 Vixualogic's screens in the 2nd row of my wife's car.  They connect to a visualogics control box via a DIN cable.  I want to upgrade my system to handle more monitors and a while back I bought and audiovox video switcher.  Only problem is, it outputs on RCA jacks not DIN.

Any idea how I can get an adapter to convert my DIN connectors to accept RCA or are they totally proprietory to vixualogics.  Really want to use the fancy switcher as it will allow 4 inputs to each TV and I've got a VCR,DVD, & 2 HD players and kids that want to watch different content.

I'm going to sit down and see if I can continue to use the visualogics box by setting each TV to a different input (it allows for 2) then connecting the inputs back to the switcher.  This might just be the easiest way to do this and would solve my problem completly.  I have to diagram this and see if it will work.  I may have just  solved my problem by typing in my question and thinking it through.  Would still appreciate anyone's comments
