Already have a C-120 Raymarine display on boat functioning perfectly displaying Sirius weather, radar, GPS, and sonar. I am going to add a second C-120 so I can have a better "dedicated" picture of radar especially running at night. Question is, do I hook up radar lead directly to additional C-120 now and how then to interface with the existing unit? Use seatalk cable or NMEA. Will any of the displays from the existing unit then display on the additional unit? Any advice is appreciated.... :confused:
