My NMEA 2000 system operates well. The system is just running at 12% when I do the tests. I have all the NMEA 2000 data on all instruments on the NMEA 2000 net. So the data are there.
I do not get my position and course over ground from the GPS receiver which is connected on N2K backbone, neither on WIFI or NMEA 0183. i can confirm that i do have the GPS signals transmitted on the N2K network. I get that info on all other N2K instruments. It worked some time but not very reliable, i can see the position lost some time.
