Hi,
So if you are someone that takes your bike and garmin on holidays, how do you change the Routable Cycle map? Mine has the Routable Cycle map of Europe by default but I want to add / change to the one for Australia. How do I do it?
That's standard across most GPS manufactures and ranges, for example Garmin and TomToms automotive devices come with the maps for specific areas. If you want other maps you have to pay.
That's why many folks use OSM mapping.
