Chart plotter just developed a fault.
About every 5 minutes the plotter flicks off and then restarts, and resets to factory default settings.
Most of my routes have gone, but the waypoints are still in place.
Will not "follow route", and if I try a "reverse and follow route", the following message is displayed: "Selected route
cannot be modified at this time".
I think the chart plotter will need to be returned to Raymarine
for a fix, but just in case, thought I'd post here in the event that some one else knows of this fault, and what the likely fix is.
