Basically an item with a map icon and a small map model, that triggers an event 'OnMapOpen' much like how the remote add-on does it, when clicked while equipped. This would allow the player to link that event to showing a map via camera events (so the map is physically built out of bricks).
All in all just a fancy remodel of the remote item. To stay in style a simple 2x2f print model/icon would be nice.
Thanks in advance.
