How to get lighthouse_id.txt file on microSD card when using any Raymarine Dragonfly model

Article FA22114, July 6, 2016

In the Dragonfly unit's Chart menu screen, select the Lighthouse base map option.


The Raymarine Dragonfly may function a little differently than a-series, c-series, and e-series models in terms of writing the critical lighthouse_id.txt file to a microSD card.

With the Dragonfly turned on and the microSD card already inserted, go to the Chart menu screen, select the Lighthouse chart base map option. Without any particular message or indicator, the lighthouse_id.txt file gets written to the microSD. 

When you take the microSD back to your computer, Lighthouse Manager will see the validity of the card as a target for downloading charts and let you start downloading your chart subscriptions.
