Road Pilot?

I have the binatone 450 Carrera. I am very happy with its features but now the " road pilot" says Locked?When i press the symbol it tells me to enable this service and go to www.binatonecarrera.com and update using an ID ref, which I have. But I go to the site and there is no section askling me to update, can you help?
Kind Regards

John
