Basecamp and 66st - Custom map

I have a 66ST. I've installed an OpenStreet map to the 66ST through basecamp. The map shows up in BaseCamp. Says installation is done. On the 66st the, the SD card shows a garmin folder. Inside the folder is the US Mountain OSM Topo.img file. The file size is 1,678,944 KB.
I've installed the map twice and it the 66ST is not recognizing the map file. It's on a 128 GM SD micro card.

How is the card formatted? Your device needs the card to be formatted FAT32 and cards of that size aren't FAT32 by default. That will be the problem.

Can I format this card in FAT 32 with Windows 10?
