You will also need to load the Flash 200 tool that is shown further down the Trimble page to your laptop. Connect your laptop to your Nav with a $10 serial cable that is a nine pin and you are good to go. You can also download latest Nav firmware to laptop and if needed, update your Nav with this same connection.
