OEM DVD player

[deedst4r]

So i have a dvd player right behind the sunroof on the ceiling. I have never used it but i plan to use it soon so i am just wondering this.

Does anybody know how to work to sound? In the gmc that i used to drive there was a radio ration i had to tune to that made the sound work. Does anybody know?

Thanks y'all very much.

Your sure it's not just rear seat audio?
