I have a Echomap 95UHD and a GPSMap 7410xsv. They both have modified firmware and can load any unlocked Bluechart maps.
I can't get them to display Australian topo maps (genuine or unlocked) in the chart navigation screen like you can do with North American topo maps.
The map is recognized as a supplementary map but doesn't display.

Topo Maps on Echomap and GPSMap Chartplotters

Is there a map id I can change them to so they will display? I'd love to have a 10 inch map display in my 4x4 for off road!
