The question is, what data can the display show?
I have ordered the rs11 for integration with the i70, since the i70 will display everything that the rs11 will output, as it will be connected to the 20b Westerbeke.
The story is that the Raymarine spur cable will simply
plug into the output from the rs11, and you are good to go.
Of course, it'll take 11.7 months to figure out where to tap into the
wiring harness on the red devil, since I am not replacing the existing gauges, and calibration of the rs11 proper.
