you get nothing thru northstar that you don't get from VV - the parts are also spotty to get (last one I did for a customer , the gateway was on backorder for 2 months) aftersales factory support is virtually nil....
besides that, I do engine data on many units these days in my job thru Maretron. Most customers tell me that after the novelty of looking at the engine data on their chartplotter, they go back to their gauges as they are redundant and they don't have to flip back and forth on their chartplotter. And having all in one, means of your chartplotter goes down, so does your engine data...
rumor is Raymarine will go smartcraft in 2010....
are these NMEA2000/J1939 engines, or is there something that maretron offers for smartcraft (google says no)?
