Hi everyone, I'm trying to install the north american map on my Garmin gps60Cx but it doesn't detect what I've copied on the SD card. Do I need to do something on the GPS like format it ? when I go on map information it doesn't show anything.

How can I know if the map have been installed correctly?

Corrently I've pasted gmapbmap.img, gmapprom.img and gmaptz.img in SDcard:Garmin/
