Every entry in the Business Directory has a reference so you can easily locate them on this map, the reference looks like this M1-J5-7-4
M1 is the reference for Map 1, there are 6 maps M1- M6, J5 is box J5 on the map below, if you now imagine a grid within that box (like the one opposite) then 7 is in the A direction and 4 is in the B direction.
