Comnav 1420

I currently have a rdp-139 connected to the comnav 1420 autopilot. I want to upgrade the display because I need more detailed charts. Which displays will work with my autopilot?

You will need to output NMEA0183 to drive that pilot. Any of our models can do this, however some, like the TZT require a NMEA2000 to NMEA0183 converter.
Our GP1871F, GP1971F, and all TZT2 models already have an NMEA0183 output so no converter would be required.

Thanks for the reply.
