Garmin Echomap 50, Navstar CB202 Interface

Postby Ja Venter » Sat Sep 10, 2016 1:56 pm

Good day. Hope everyone is well. Please be so kind as to advise me regarding interface options between the Garmin EchoMap 50s chart plotter and fish finder and the Navstar CB202 radio for [providing] GPS position.

Can this be done?

Is there an interface function?

Any advise is greatly appreciated. Thank you and regards.

If you can point to a source of on-line information about the NAVSTAR CB202 radio, I can probably help you. I believe that radio is an obsolete model, and the manufacturer no longer exists or is no longer active in the recreational marine communication radio business.

You should consider updating your VHF Marine Band radio to a more modern radio that complies with the CLASS-D Digital Selective Calling specifications. Older radios often only comply with less stringent recommendations. Considering that the cost of a new CLASS-D DSC radio is barely over US-$100, investment in a new radio may be a better route to integration of your chart plotter and radio.

For information on using NMEA-0183 interconnections, see my collection of information on this topic for a great number of chart plotters and radios at
