[CA] [CA11] Navionics: Cannot remove/adjust red dotted warning depth area

[Chuck - Raymarine - Moderator]

Randy,

Unfortunately, our only copy of Navionics cartography including Mexican waters is a Navionics NAV+ chart card which has been populated with cartography for the US and Canada. This chart card only provided limited detailed cartography of Baja and provided no detail further south. I would recommend making comparisons with the Chart Viewer on the Navionics web site as a first step when cartography issues arise. Features such as those within your screen snapshots appear to be very consistent with what I see with the Navionics Chart Viewer (see below) for Mexican waters. It appears that the dotted areas may be indicative of areas lacking detailed cartography, and as such may not be configured OFF via any of the Chart application's Objects settings. As suggested within another thread which you had posted, these MFDs are compatible with not only Navionics cartography, but also with C-Map and LightHouse Charts. It may be possible that one of these other cartography sources provides better cartography for Mexican waters.
