Put a heading sensor on the boat a week or 2 ago. Got the wiring diagram from KVH and it is not “plug and play”, it must be wired old style. I hooked it up as directed but don’t believe it is working properly. Some of the gauges/units of measure are off. I was given instructions for hooking the the NMEA out on the heading sensor to the NMEA out on the head unit, kind of makes sense, but, wouldn’t you want the heading sensor info going OUT and the head unit info coming IN and using that info. The head unit does recognize that something is hooked up as it now asks me if the autopilot is active, so something is going on. Any help b-4 I crawl back in the console?
