I bought, "TOPO Australia & New Zealand: Download", and loaded them on my Garmin 76CSx. The maps work well on the device, but on BaseCamp, the only available map is 'Global Map' (the device is connected).
The device shows up on the list but the prompt to transfer the maps using the "Receive from GPS" button is grayed out.
Waypoints, routes etc are syncing; the device is connecting.
How do I get the detailed maps to display on BaseCamp using my Mac?
