Setup Arrow On Apple Device
1. After powering on the Arrow Device, go to the Bluetooth settings screen on your apple device and select the Arrow device.
2. Now sign into Diamond Maps and turn on GPS using the Yellow GPS button on the right side of the screen. Test to make sure it is using the Arrow device and not the apple devices location. To test leave the Arrow device in one location and walk away from it with the apple device and make sure the yellow dot on the screen doesn't move.
