I have a Lowrance 3500C and I cannot find a compatible map card for it. Navionics indicated they have one that works but it does not. I know this outdated card "Lowrance NauticPath USA Marine Electronic Chart" does work because my neighbor has one and it works great. However, it is encrypted to not allow copying and no body sells them. If any one knows of a solution or has one for sale please let me know
