Custom GPS

[Meatball0311 79]

I am making a custom GPS and I config it ingame.  The question I have is where do I find the config for the picture that is displayed on screen when you activate the GPS.

 

This is my config so far:

class SOC_GARMIN401_GPS: ItemGPS {
		dlc = "SOCMOD";
		author = "SOCMOD";
		_generalMacro = "SOC_GARMIN401_GPS";
		scope = 2;
		displayName = "[SOC]Garmin 401 GPS";
		descriptionUse = "Use: View GPS";
		simulation = "ItemGPS";
		picture = "\A3\Weapons_F\Data\UI\gear_item_gps_CA.paa";
		model = "\A3\Weapons_F\Items\gps";
		descriptionShort = "Enables accurate positioning.";
	};
};

would it be the simulation = that decides what picture is used and where do I config that?
