I just purchased a map download from Tasmap, assuming I'd be able to load it on to Backcountry Navigator Pro. After going around in circles with no success I emailed for help and got an answer that explained everything: "We cannot process KMZ that is an image overlay. We do not claim to."
So, is there another way to load these maps into this app? I did flirt with Orux a while back at the suggestion of others on the forum, but I found it much less intuitive than Backcountry, so I'd rather not switch.
Backcountry does have inbuilt Tasmania maps (and I've found their maps to be good generally) but thought that I might like the Tasmap for a planned Arthurs traverse.
Thanks.
