In all data usage, it's important to update websites visited regulary. As we develop our onlinebooking continuosly, you need to update our portal to have access to the latest features and services. If the booking/cancellation of the trip "doesn't work" as desired we recommend you to mark the address field of our homepage and press the F5-button or click the round arrow in connection to the address field. If you don't have access to this button or symbol on your computer, mobile phone or tablet, you should contact your dealer for information on how to update the browser and it's system via the settings in each unit. Good luck!
