Papago P3 Map Data

[Prioleau]

Hi - I bought the papago P3 but there only seems to be map data for the US, Canada and Asia. I wanted to know if it's possible to load the correct map data for my country (Zimbabwe) onto the P3 and if so, how do I do it? I thought of exporting map data from somewhere like OpenStreetMap which I can do but that exports into XML or other format so now to get it onto P3 is a story!
