You can use the zones.inc to enable GetPlayer3DZone function and from there add a textdraw, timer and variable that checks if the player has GPS enabled, and if so when the timer is triggered (every 1-5 seconds) it updates your textdraw with the result of GetPlayer3DZone.

zones.inc can be found here:
