Has anyone either Flip Down DVD player or DVD player in the headrest of the car / van / truck / SUV? If you do me the pros and cons of them. We are trying to either of our Dodge Caravan Sport for long trips we take with 3 children received less than 8 years. If you could also enter the amount you paid, where you get it, and where you have installed and the cost of the instillation. Thank you!
