I am about to purchase a 2WD SE and am probably adding the Utility Bed package and also the Popular Package (captains chairs). I do have some questions as to the dual media that is in this package. The dealer wasn't able to explain it in more detail and the brochure really doesn't say a whole lot about it. So with that being said can someone please explain what it is actually? It also mentioned something about wireless headphones capable. Does this mean that the headphones are also included in this package or are they an additional cost? Thanks in advance.
