At this screen you will see a pull down menu with a list of different regions on it. The only ones you need to worry about are USA with buzzer and Netherlands. If you choose USA, I will give you three short quick beeps when you lock the car and one short when you unlock it. Netherlands will give you three longer beeps when you lock the car and one long when you unlock it. Personal preference on which one you like. Here i select USA with buzzer.Then hit F3
That’s all finished ! Hope it would help you!
