radar overlay

rmpoole1,

The MFD's Radar Overlay feature is not dependent upon the cartography contained within a Navionics chart card. The function key having the options RDR/CHRT/OFF which you have described is the Chart application's Sync feature. When configured to RDR, this feature is simply designed to match the radar range to the chart range. Use of the MFD's Radar Overly Feature is not dependent upon the configuration setting of the Sync feature. In order to use the Radar Overlay feature, the MFD must be:
- interfaced to a compatible radome or open array pedestal
- the MFD must be interfaced to a source of GPS data and must have acquired a GPS position FIX ... verify this by examining the FIX Status field of the GPS Status dialog (MENU->GPS STATUS)
- the MFD must be interfaced to a source of Heading data ... verify this by configuring the MFD display the Data application and then configuring the Data application to display the Navigation data panel ... the Heading (not to be confused with COG) data item should be verified to be populated.
- the radome or open array radar pedestal must be powered ON (POWER->SCANNER->ON)
- the radome or open array radar pedestal must be transmitting (POWER->RADAR->TX)
- If interfaced to a HD Radome or HD/SuperHD Open Array Radar Pedestal, verify that that the Dual Range radar feature (from Radar application page/pane PRESENTATION->DUAL RANGE) has been configured to OFF.
- the Radar Overlay feature (2D CHART LAYERS->RADAR OVERLAY) must be configured to ON
