Broadband Radar: Chartplotter Compatibility
A Raymarine C70 Classic chartplotter and radar was on my 28 foot sailboat when I bought it last year. In terms of electronics, this is pretty old stuff, and I'm attracted to the new toys (have my eye on the new Garmin 741xs).
I also like what I read about broadband radar (4G), particularly for my usage pattern, but at the moment, it doesn't look like anyone but Navico is making them. I imagine that the other manufacturers are working on broadband technology, which brings me to my question:
If I were to purchase a new chartplotter (the Garmin 741xs, for example), and then Garmin came out with a broadband radar in a year or two, would it be likely that the chartplotter would be compatible? Or would an entirely new chartplotter likely be required?
I realize this is fairly speculative, but to some extent would be determined by how dependent the radar is upon the chartplotter to function (in other words, does the chartplotter run the radar, or does the radar basically do it's own thing independently, and just display the readout on the chartplotter?).
