Question about Raymarine RL70CRC GPS Receiver
I have recently been having a problem with my CMap Cards seems the charts is not recognized by the unit. sometimes is shows correctly mostly the unit turns on and will not show any chart details as if not card is in the reader. Sometimes it is working correclty but when I change the range or hit another soft key button the unit resets to same problem, chart? Very frustrating and could be dangerous if it happens at a bad time. Has anyone seen this. I have tried doing a full reset of the unit, cleaning the card contacts. Could it be some kind of fault in the wiring or the connection box? The data boxes seem to be showing correct position and heading etc. Radar work fine? Any help diagnosing would be appreciated.
There is a feature in these chartplotters called "Plotter Mode" that is often misunderstood and causes the exact problem you describe.
Press menu.....chart setup.....and scroll to the bottom until you see Plotter Mode in the list of options. It should be set in the OFF position.
If you have more than one display networked onboard check the setting in each one invividually.
What Plotter Mode does is allows the chartplotter system to access range scales not supported on the chart. It is not normally used for map-based navigation but more so for chartless electronic plotting (it can display routes, waypoints and track-recorder breadcrumbs.) open-ocean cruising, or for ultra-precise GPS operations (like a precision anchor drop, finding a very specific location etc. When plotter mode is on you can zoom in to a very, very small working area. The indicator it is enable is the cross-hatch background on the screen, the lack of map information, and the NO CHART DATA watermark on the screen.

It could indeed be the "Connection" I would check these out properly, but with such a "Mission Critical" device I for one wouldn't muck arround, and get it back to the manufacturers and have it "Serviced"
