Rear seat DVD player
 

Bought a new Q7 with no rear seat DVD players.
Planning to buy one (after market ones). I found that head rest poles are bulky and also rectangular. So most of the after market players dont fit. Except old model Phillip which uses a starp to tie. Does any one used any thing better. All suggestions are very much appreciated. 2000$ for just a DVD player is too much and out of my budget, thanks.
