Firstly, make sure your DVD have built-in IR wireless module so that your headphone can receive the audio signal from your DVD player.

Second, it should be clear which frequency transmitted from your DVD player. Generally speaking, there are two frequency of IR transmitter.One is 2.3MHz/2.8MHz. another is 3.2MHz/3.87MHz. Only emission frequency same as receiver can receive the audio signal.

do you have the remote?

We have a GMC Envoy which also does not allow us to play the sound from the dvd player through the car's speakers. Although we purchased the vehicle new with the dvd player already installed, it was installed by the dealer, making it after-market. I assume those that were installed in the factory work differently. Maybe this is the case with your's as well. Good luck!!

i have a 2005 f-150 and it was bought used, no wireless headsets and remote but i learned if you push buttons 2 and 4 together on the cddeck you can use the radio through the speakers and the kids in the back can used the headphone jacks to listen to the dvd player.
