Using older Fishing Hotspots with EchoMap 73sv.

[jbird68]

I have Fishing Hotspots installed into base camp for an older Garmin Quest GPS unit. But I would like to use it on my newly purchased EchoMap 73sv. I don't see an option to install it on the SD card. There is no unlock code needed for the hotspots. I am guessing it is incompatible with the EchoMap. Anyone been able to install it in a card?
