Hi all I have a HDS fishfinder which I need to update to run my new toy a sidescan on it but the software needs to be 2.5 or later,mine is 1.5,but does not have a SD card slot.If any member has a hds plotter which takes a SD card they can update and if I link mine to theirs via ethernet cable then that will update mine.Any help would be great otherwise I`ll have to send to Navico
Thanks for any help guys Nige
