I am slowly learning about the features my 05 exl navi has. as I was vacuuming out the car, I found hidden away a cd changer under the drivers seat, and a dvd player under the passenger seat. I read in the owners manual that the exl navi does have the option of a rear entertainment system, but since mine does not have a screen, and the cd changer and dvd player both appear to be stock, what should I do with these? my radio already has a cd slot and a cassette slot as well. but the dvd player is what caught my eye. any advice would be helpful.
