Electronic charts & SSB weather
I have just installed a Raymarine C70 color Radar with Chart overlay, hooked up via nmea to my existing Navman instruments and an octopus auto helm. All the wiring was easy and works as Wind Vain steering, GPS rout, or steer to compass. I have wired the NMEA back to the chart table soon to add the PC side. If you have any questions I have researched quite a bit.
