Now that my audio issues are resolved its onto the speedometer. The pitot path is completely unreliable with my Smartcraft speedo. I'd like to join to the GPS world. According to my documentation the SC1000 speedo has a NMEA input interface (2 wires, blue and white) and my Raymarine SL70CRC has a NMEA output connector with pins 2 and 3 as NMEA_SIG and NMEA_GND. Is it just a matter of connecting those two together to get GPS into the speedometer? I have not dissected the dash yet to make sure the NMEA interface on the speedo isn't connected to anything. But base on its response to the CAL settings I try, it is not connected. Thanks in advance.
