Rep Power: 364

My friend and I are doing some work on his 1996 BMW 3.28i. He's putting a motorized screen where the head unit was. We're looking into intsalling the head unit in the glovebox. Now here's my question, does anybody know BMWs well enough to tell me what is behind, above, and below the glovebox that we cannot see? If its not going to be worth the trouble, I don't want to take the whole dash assembly apart. Thank you.
