Thank you. I've been reading, but unfortunately, my device came today and in a few hours I'll have to be behind the wheel. Thus I am very limited from time in order to resolve my issue, as I do not know if the truck will be with GPS equipment, and at the moment I do not have the option to buy any professional GPS system.
Thus I have raised this thread in a hope of someone to provide me with a link or more detailed guide on how to update my map/ftr files.
