I've replaced two Lowrance 9 ti2 units with two echomap 93sv uhd units. Originally I had a powered nmea 2000 connection so when I made a waypoint it showed up on both screens. With the Garmin's I can't seem to make a connection to do the same thing with the nmea 2000. Do I need to ditch the nmea 2000 and network it with the panoptix ethernet ports using a network cable? Before I buy the cable I want to make sure it's not capable of linking with bluetooth or wireless somehow. Thanks!
