Hi I recently purchased a 2001 Lincoln Navigator, that includes an Audiovox DVD Player, unfortunately It only came with one wireless headsets, I have checked various website such as ebay, amazon,ccraigslist, kijiji, and so on, but the onces listed are either broken, minor damage or as is, does anyone know anywhere were I can get affordable headsets. Thanks! Or does anyone know if the Dvd Player can be played without the headsets. Please advice??thanks!
