E80 Depth Contours Missing

[tholley55]

Hi, I've had this unit for three years and it's worked fine - but now the depth contours have gone missing. Have tried all the settings I can fin that without success. Any advice on this would be much appreciated.

Thanks

Welcome to the Raymarine Forum Tim,

The reported issue may be indicative of a software setting/fault, a problem with the MFD's chart card reader, or a problem with the chart card. The MFD's memory card reader may be tested by commanding the MFD to save any waypoints, routes, or tracks stored within its memory to the Navionics chart card. Should the MFD report that it successfully completed the command, then it may be assumed that the MFD's memory card reader is operational. Should the MFD's memory card reader be determined to be operational, then it would be recommended that a Factory Reset operation be commanded to restore its ability to display detailed cartography from the Navionics chart card. However, should the MFD's memory card reader be determined to no longer be operational, then the MFD would need to be replaced, as Raymarine's Product Repair Center can no longer service the memory card readers of E-Series Classic MFDs.
