I'm just playing around with the new hema explorer app. I messaged hema to ask if I can use my hema hema raster maps which I already own. They said no.

Keeping in mind these maps in dvd cost me $199,and app was $49.

However me and a mate are pretty confident we found a back door way to be able to use them. So far so good. However a rooted android device is needed to disable and enable certain app modifiers which normally you would not have access to. Bit of mucking about but it works. Although much easier to use these maps on Ozi.
