[CA] More than one Nav DB card in a Networked E80/E120 System

[Chuck - Raymarine - Moderator]

Welcome back to the Raymarine Forum Lothar,

A prudent mariner will maintain the vessel with charts and publications (both paper and electronic) which are current (i.e. updated from USCG Local Notice to Mariners and electronic updates from the cartography manufacturer (ex. Navionics, C-Map, LightHouse, etc.). Accordingly, it would be recommended that problematic chart card be replaced and that the older chart be stored onboard (outside of the MFD) until such time that it may ever needed. Caution should be exercised when using older cartography, as may not accurately reflect navaids and hazards to navigation.
