I currently have a Raytheon Pathfinder RL70C radar/chartplotter that came with the boat. It is the original version, not the ugrade to plus. It also has 2 NT+ chart cards in it that work fine. However, the raymarine website and landfall navigation says I need the plus upgrade to use these. I realize I will not be able to use all the functions of the NT+ but can I use these chart cards? Thanks ahead for the info.
