I have a 2013 Town and Country with the 430 RBZ radio. I would really like to be able to have a video playing in the back with headphones and the audio such as the radio out of the main speakers (It plays the video through the main speakers). I read on someone else's post to push the headphone button on the remote but this only mutes the head phones. Can someone PLEASE HELP!!! I am a bit technilogically challenged as you can see but have listened to the Tinker Bell movie one too many times this summer!
