C80 Classic A50D classic MFD

[navyguy28]

we currently have these two MFD's installed on our boat there are currently no charts being produced for the region we live in Great Slave Lake

is there a way to regain chart functionality for these MFD's without a chart card? gps position currently shows us always in the middle of the lake on the base world chart

thanks

Welcome to the Raymarine Forum navyguy28,

Please note that without a compatible Navionics Chart card present within the CF memory card readers of your displays, they will be unable display any detailed navigational cartography. However, as you can see from the screen snapshot below taken from the Navionics web site, there appears to be at least some cartography available for Canada's Great Slave Lake:



Accordingly, it is recommended that this be confirmed with Navionics and if so, that'
- your MFDs be updated with the latest available Raymarine product software updates, and
- a Navionics+ chart card be purchased and then updated with Navionics Freshest Data Updates for geographic area in with Great Slave lake resides.
