Yes, that won't make any difference having your Washington maps loaded. You just won't have any kind of map for Arizona. The GPS still knows where you are, you'll just be looking at a blank screen. You can still use it to find your way back to your vehicle, or to any other waypoint you may set. Also it's nice when you don't have any maps to drive around with it on in your hunting area so you can at least see where the roads are.
