Has anyone successfully connected any nmea 2000 device to a lowrance x510c fish finder? I believe that there is a software issue as my x510c only intermittently recognizes the nmea device(s) on the network. I have tried troubleshooting all connections and swapped ep-65r sensors, Ts, and resistors with no success. Hard reset on x510c also tried. As my x510c is more than a year old, Lowrance wants $212.00 sent in with the RMA package just to look at it.
