[CA] [CA11] Multiple Navionics charts in e95/e7?

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum Hartley,

The design of LightHouse II software should generall support having a second Navionics Chart card present within the MFD's memory card reader or within the readers of the system's MFDs. While only one Navionics Chart chart card will be listed within the Chart application's Chart selection feature (this is simply a feature ... don't worry about it ... just select it), the Chart application should be able to display all Navionics Nautical Charts within the system. Accordingly, one should expect that if the Chart Boundaries layer has been configured ON and that if ranged out far enough to view the geographic areas covered by each chart card, that chart boundaries should be rendered corresponding to the cartography for each chart card. One should also find that when one ranges into an area only supported by one of the chart cards, that detailed cartography for the corresponding area is visible ... test both areas. In areas having overlapping coverage, the LightHouse II software should utilize cartography from the chart card having the most current Freshest Data update.

This said, we have received reports where chart data from a second Navionics chart card within the reader of MFD within the system not being able to be accessed via the system's MFDs. In such cases, the issue is often resolved by inserting both Navionics chart cards into the Data Master MFD's memory card reader. Unfortunately, this sometimes does not resolve the reported issue and it would then be necessary to operate the system with only one Navionics chart card within the memory card reader of the system's MFDs. As there is generally significant overlap in coverage provided by Navionics chart cards, this limitation generally has limited or no impact upon the practical operation of the product.

In contrast, LightHouse Charts are designed to be individually selected for viewing and only one LightHouse Chart may be selected for viewing within a single Chart application page/pane.
