kiwi_ferg,

When using the display, the chart card must be present within the display's memory card reader. C-Map Cartography selection within Dragonfly 4/5/7 Pro displays is accomplished via the command sequence OK->CHART SETTINGS->OK->CHART SELECTION->OK->C-MAP 4D: NAVIGATION CHART->OK. Detailed information on this subject may be found within Chapter 9.10: Chart selection of the Dragonfly-4, Dragonfly-5, Dragonfly-7 & Wi-Fish Installation and operation instructions. Following selection of C-Map 4D cartography, the Chart application should be used to determine whether any detailed cartography is visibe. If not, then it would be recommended that the Chart application be re-centered on area in which it had been used by its previous owner in case the owner reconfigured the C-Map chart card with local data rather than the regional data with which it had been originally populated. Should no detailed charts be visible, then it would indicated a fault with the chart card or fault with the display's memory card reader. The display's memory card reader may be tested by using the display's screen capture feature shown within the Chapter 7.7 Shortcuts page (accessed by a quick press of the display's POWER button) of the Dragonfly-4, Dragonfly-5, Dragonfly-7 & Wi-Fish Installation and operation instructions. Should the display report that it was successful in saving the screen's image, then the display's memory card reader would be deemed operational and therefore indicate an issue with the chart card (either conversion to a Local card by its owner or a failure of the chart card).
