Hi. I have a C90W on my sailboat connected to SH 2150. Both were installed new 4 years ago. Recently I have noticed something strange. When the plotter is zoomed in...say to 1/4 mile range....the AIS targets disappear. I still get the "dangerous target" alarms and screen pop up, but no AIS info. If I zoom out, everything is normal. This never used to happen. Any ideas?
