I've had several similar units, and used them with Navionics HotMaps Premium series chips. You must select Menu. The "Browse files" to access the MMC card option. Once the selection screen opens, choose which card or file you want.

FYI...All of Lowrances HD models come preloaded with pretty much every major lake and river in the US.

Lemme know if this helps...
