Dragonfly 5 Pro with Nav+ Does Not Display Sonar Chart Data

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum Tim,

First, it is recommended that you verify that your Dragonfly display has been updated with the latest available Raymarine product software updates, and if not update its software accordingly. Should the display be operating with the latest software, and should the problem persist, then the display's microSD memory card reader should be tested to ensure that it is operational (recommend testing by commanding the MFD to save a screen snapshot a microSD memory card within its reader ... if unsuccessful, it will respond accordingly). Should the display's microSD memory card reader be determined to not be operational, then the display and chart card should be sent to Raymarine’s Product Repair Center to be bench checked / serviced. Should the above have all been satisfied, then it is recommended that rather than downloading the SonarCharts for individual lakes onto you Navionics chart card, that the chart card's contents be erased via the Navionics Chart Installer and that the Navionics chart card then be populated with Navionics Nautical Charts and Sonar Charts your state and the bordering states around you. Should the problem persist thereafter, then please identify the name of the lake and state in which it is located in order that we may attempt to duplicate the problem.
