Look like the Invision aftermarket units. You won't have control of them from the dash unit. They both are self contained units that let each rear seater watch a different DVD headphones should have A/B channels. You can also slave one of the units and watch same dvd on both headrest units.
thanks for the information. I press on the power button on each unit and they don't come on. It is like they are not getting power so I was thinking there was a main switch somewhere. Rexster, I see Texas gulf coast. We love Port A!!!! :blob:
