Thought I'd post links to some wireless headphones that are reasonably priced and are fairly comfortable plus they work with the built in IR transmitter .

If you have rear controls you should have the factory IR transmitter. You can verify for yourself by using the nightvision on a video camera. You'll see the trasmitter shine like a light bulb when you look at it through the night vision function. I'm 99.9999% sure you will have the transmitter.

I can't tell you how to determine which headphones work or not. I've only tried the Bravo one's I posted above and some sony mdr-0230's I've heard audiovox work. I think most must use the same signal so you are pretty safe with whatever one you get...just make sure it is IR and not RF.

I had the dealership install a dvd player in the back, can this be played through the factory speakers and if so, how do I do it?

If they did it correctly just push and hold the Rear AV button for more than 1.5 seconds. If they didn't install it correctly I have a how-to link in my signature.
