I'm looking to add a DVD player and an LCD screen, maybe 7-10", to the family van for those long drives on family trips. It's a Dodge Grand Caravan. The audio system in it is great, IMO. (10 speaker layout by Infinity) What features do I need to look for? What brand/model? I'm not interested in adding a center speaker. I'll be happy with stereo models. Same questions go for the LCD screen. I'd prefer a flip down model. Thanks BTW: I'll be leaving the double din stereo in the car and adding the DVD player in an empty slot below it.
