This might be a stupid question, but I'm trying to upgrade a Hummingbird Helix 7 and the directions don't tell me if I should open the bin file that is download it from the Web before I put it on the SD card. Advice ? If I open the files and put all the open files on the SD card and then insert that into the hummingbird unit, does it automatically know which to install to the unit?
Thanks
