The reason i make this suggestion is because nearly all players generally have a Map open in their browser that they alt+tab to anyway, so this would make the in game map actually have value and be worthy of having/collecting the pieces of to make a full map.
I would like to play DayZ without tabbing out constantly to figure out where i am on the map. With this feature i would (and i believe others would) begin actually using the in-game map.
