Thread: zip files, MDC app

there is a deal on the MDC web site for downloading the brush piles on a lake, I can get the zip file, but after I open it I can not transfer it to a SDcard to transfer to my gps any help would be appreciated

You have to unzip that file and convert it to a usr file . I downloaded some software from lowrance a long time ago to do it with,but I know there are other software that can do it also
