HI

we bought our voyager yesterday, its a 2005 crd se plus. it has a largce screen dvd player on the roof, which displays car show. it came with 1 set of wireless headphones, and a remote control. The dvd loads up fine, starts playing but We cant work out how to get the dvd to play sound through the speakers rather than the headphone. my 3 year old refuses to where headphones! can anybody help??? also where can i buy extra headphones?

 

OH ALSO, does anybody know where i can get a copy of the cars owner manual??
