ActiveCaptain and Garmin Express
The ActiveCaptain and Garmin Express apps help you manage your Garmin chartplotter and other devices.
ActiveCaptain: The ActiveCaptain mobile app provides an easy-to-use connection between your compatible
mobile device and your compatible Garmin chartplotter, charts, and the Garmin Quickdraw Contours
Community (
). The app allows you to monitor and track your boat with the
OnDeck
™
system. The app provides unlimited access to your cartography and a quick, mobile way to
download new charts using the OneChart
™
feature, provides a link to receive notifications on your chartplotter,
and provides access to the ActiveCaptain Community for feedback on marinas and other boating points of
interest. You can also use the app to plan your trip and sync user data. The app checks your devices for
available updates, and notifies you when an update is available. You can even control the chartplotter using
the Garmin Helm feature.
Garmin Express: The Garmin Express desktop app allows you to use your computer and a memory card to
download and update Garmin chartplotter software and charts (
). You should
use the Garmin Express app for faster data transfer of larger downloads and updates, and to avoid possible
data charges with some mobile devices.
