So my first mod was a flip down DVD to keep the kids quiet. They have headphones but when more than 2 want to watch, the audio has to play thru FM and it sounds horrible. My question is can I connect it somehow to control through my RER? I would like to be able to link them so audio plays like it does when I have a DVD in the HU and I'd also like to control the settings from up front. Is this possible? Thanks
