I know you can download it for free, but that does not allow you to use it after the 30day trial period is over. I know it's kind of hypocrite, but if there is an opensource free alternative I will prefer that. But thanks for your advice.
BTW: I got the USA_Canada_Mexico map working, but adding a country like Mexico and the map is the same size, that must mean that some detail or something has been left out compared to the USA_Canada map and then that one again compared to the United_States_2GB map.
