I've got a Raymarine system built around a couple E80s. Would like to add a wind instrument that can show true wind, ideally through the E80s.
I believe the official Raymarine solution is to buy an i40/i50/i60. The i40 would be the cheapest and make the most sense - because I don't care about the quality of the display.
Anyone have an even cheaper/more creative way of getting the data I need into the E80s?
