Ive lost the rcmmc with my Navicore software on it, but the Navicore website ( http://www.navicoretech.com/Consumer...770/en_GB/770/ ) gives instructions for downloading and installing the software. Part of the instructions says, "Extract the application file to the root of your memory card". What is the "root" of my memory card, and how would i do this. Any help would be much appreciated. Thanks!
