Raymarine C120 Radar / Plotter - GPS source

[superheat6k]

Thought I would ask this here rather than PBO Forum as these are more likely found on Mobo's than raggy things.

Boadicea, my new to me Corvette came with a lovely C120 radar plotter circa 2006.

After pulling my hair out most of Saturday I finally found out the reason I had no GPS plot was because I had not turned on the ancient Garmin C232 plotter, which is apparently providing via NMEA0183 the GPS data for the C120. Two plotters on to cross the Solent seemed a bit of an overkill !

I would have expected the C120 to include its own GPS data source.

So I have this modern(ish) C120 sat next to a steam driven Garmin back & white plotter both sharing the same data. What is the easiest way to get rid of the Garmin and de-clutter the chart area ?

Either wire the old antenna directly to the C120 via NEMA or buy a new raymarine GPS ariel and plug it in via seatalk

This was fairly common practise during the time of the "classics", the Raystar GPS 125 receiver with 0183 and ST output generally used with them was relatively expensive so people often used an available 0183 source if they had one and saved the money. I suspect you may have difficulty sourcing one at a sensible price, there are a few on US ebay at between £150 & £200 + shipping and one on UK ebay (used) for auction with a start price of £150. Probably best to replace the Garmin source with an 0183 GPS puck for redundancy.

Thanks, but I am going to keep the Garmin as the NMEA0183 data source. To avoid clutter and make way for a TV on rising brackets I will re-locate it into the cupboard below the dash platform, but I will keep the leads long enough to be able to use it should the C120 ever pack up.
