Is there still no way to convert a modern NMEA2000 signal into an old Fastnet signal? I'm considering upgrading my H2000 system to H5000 but it's really more money than I can motivate to swich everything at once. I would like to use my old 20/20 displays for bsp/TWA/AWA and Target speed/ Optimum wind angle if possible. Is there really no way to use the older displays with the new processor? I'm seeing sailmon can interface with both N2K and Fastnet, but adding a full sailmon processor on top of the H5000 Hercules seems like overdoing it. Is my only option to start from scratch?
