Hi everyone, new here and looking for help. Trying to load topo maps to my Garmin Echomap 73sv.

I loaded it onto an sd card as per the instructions using base camp, then taking sd to gps unit but gps says files not supported. How can I get the files in sync with my Garmin



I suspect that it isn't compatible with newer marine devices. See this post from Popej.
