Hello. I need help continuing to use my BlueChart G3 map on GPSMAP devices. I have the original locked map on a memory card (which consists of: a gmapsupp file, a gmapsupp.gma file, a gmapsupp.unl file, and three img files). What I want to know is how to continue using the locked map on another GPS because inside the .unl file there are eight lines of code, each 25 characters long. If anyone can help me, please.
