Johnny, working with my new transducer and DFF1 sonar, I did a reset of the VX2 and am now having intermittent AIS display on the chart plotter. I am getting AIS data on Port 2 in the Port Monitor. I've had 2 occasions now when I get a proximity alarm and all of a sudden the targets are on my display, but most times they are not visible on the chart plotter screen. I've tried the color change and the AIS targets, but no consistent result. Any suggestions?
