I haven't done it yet but it's on my winter list when we get home.
The plan is to basically mount the TV in a drawer attached to the top of one of the bays. The drawer pulls out and than hinges down. There is a already a sound system in the bays as part of the front Bose system. Motorized would be nice. It looks like I can get a 40" TV or so in the bay. Any way that's the plan. For me, it's either build in or not have one but I couldn't stand the clutter of stowing than hooking it all up just for an occasional use.
