text: We purchased these DVD players for when our grandchildren are in the car with us. They are easy to install. Just attach them to the headrests and plug them into the 12V power source. I purchased a splitter as recommended in another review. The main learning curve was to insert the DVD with the label facing away from me. Previous DVD players we used had the DVD label facing the user. Worked fine and the sound was good on the headsets. Easy to set the infrared signal to A or B in the Setup menu. A third headset we had from a previous player worked fine with this system. We like it because it is easy to remove when the grandkids are not with us.
