Coincidentally I am having very similar problem with my Nexus NX2 (mine is branded Furuno
inform me it is manufactured by Nexus). I am also getting error 03 (although I get error 02 displayed first) and system lock up. Also seems to be an intermittent fault like yours. I have checked and remade all connections, run the re initialise sequence which helped temporarily, enabling the system to run for 30 mins. Then error 02 followed a few seconds later by error 03 and lockup. I have removed NMEA
connections to other equipment
but am not finding any solutions. Sorry I can't help, I'm installing a fish
finder as a backup depth sounder
until I can sort this out. Has anyone had these issues and solved
them? The system occasionally runs for hours then locks up, any ideas?
Hope some electronics
genius can help us, this gear
is too expensive to just throw away. Tech support at Furuno couldn't help as it's a Nexus unit, and the Nexus tech guy is unavailable til mid July (a tad inconvenient as I'm cruising in coral
areas at the moment, which is great, but a bit worrying without depth
Any ideas anyone?
