Inputing Signal to "InVision" Headrest monitors/DVD's

[Darren]

My 06 H2 SUT has these InVision Headrest monitors and DVD players built in:
http://www.invisionindustries.com/products.html

I haven't got a manual and can't get an answer from their tech support.

The question is, apart from the inputs on the face of the unit, (which aren't really suitable for a permanent install) are there any separate inputs somewhere that I can utilise to attach a PS2 for the kids??

Hope someone knows something about these units?

Thanks
