I am trying to connect a new Raymarine 125 PLus GPS antenna to my Raymarine A70D Chartplotter/Fishfinder and cannot make it work. I have the power and ground figured out, and the antenna blinks green every 2 seconds, showing it has a fix and NMEA Connection. I am not using a SeaTalk network, just hooking directly up to the A70D. I tried connecting the Antenna NMEA OUT + (Yellow ) wire to the A70D NMEA IN + White wire and can not get the chartplotter to get a fix. I also reconfigured the A70D INternal GPS antenna to OFF. Any clues???????
