I have a 4008 chart plotter in a kevlacat 5.2 fishing boat. The unit continues to switch off and looses sat connection when landing off the back of waves in mid to rough conditions the unit has been repaired under warr due to a broken connector on the unit but still has the problem the connections are still very poor into the unit

n the system setup, under “UNITS” I set BEARING to “MAG” (magnetic). This will cause the unit to display course / bearing information in relation to the Magnetic North and match magnetic compass readings. It is not the same as True North! One has to be careful with this setting. There are a number of areas where the earth's magnetic field is locally disturbed, sometimes very significantly. Your GPS may not account for it. - again, under “UNITS” I set “METRIC”.

fish finder transducer needs to be on before you boot your system. check your hsb cables and termination

SOURCE: The chart plotter worked perfect for 5 yeas,

I think you have a C- Map card (black colour)clean the contacts with a contactcleaner if it not works try the card somewhere else
The C-Map card have problems that they work for a while and than stops inside the card a some memorychips and they losing contact

Check to see if this is a power issue by connecting to shore power and fully charging your batteries overnight with instruments off. While still connected to shore power, with batteries fully charged, turn on C80 navigation system. If the loading screen comes on and does not reset, then try holding down the button immediately to the right of the red power button for at least 3 seconds to see if the system re-boots.

Testimonial: "Factory reset solved the problem. Soft key next to power button worked a treat!"

Hi,

Your problem is the 4GB card. The Raymarine C-Series have a problem with their compatability tool and larger CF cards. You should use a card no bigger than 256mb.

The card probably worked in the store because the newer models accept larger cards.

Get an older card from ebay etc and copy your 4gb files onto it and try again. There is more info here: http://raymarine.custhelp.com/cgi-bin/raymarine.cfg/php/enduser/std_adp.php?p_faqid=1042&p_created=1089743435&p_sid=Y9eWB6ek&p_accessibility=0&p_redirect=&p_lva=1042&p_sp=cF9zcmNoPTEmcF9zb3J0X2J5PSZwX2dyaWRzb3J0PSZwX3Jvd19jbnQ9MjYsMjYmcF9wcm9kcz0zNiwzNTIsNDEmcF9jYXRzPTAmcF9wdj0zLjQxJnBfY3Y9JnBfc2VhcmNoX3R5cGU9YW5zd2Vycy5zZWFyY2hfbmwmcF9wYWdlPTEmcF9zZWFyY2hfdGV4dD1zaXplIGNhcmQ*&p_li=&p_topview=1
