Ok I have a 4 month old 597c hddi, I just bought a navionics hotmaps classic south dec 2004 card. I cant get it to load. what am I doing wrong. the select chart is pre set to automatic and you cant change it. please help.

hello Stephen,
my guess is that you bought that off ebay by chance? not sure where you found that card at but man thats an oldie. The classic charts in many cases of that age wont run on the newer plotters. different software set ups. the 2007 and higher will run or the Hot Maps Premium currently sold. message me if you have additonal questions and ill try to help.
