BlueChart® Mobile App Showing GPS Speed

The Garmin BlueChart® Mobile app is a trip planning tool that can be used to plot waypoints and routes using a compatible iOS device. If the iOS device is receiving GPS data from a built-in GPS chip, a Garmin Glo™, or a Garmin® chartplotter connected via the Garmin Marine Wi-Fi Adapter Kit, GPS speed will show in the app. If no GPS source is present, no information about GPS speed will be displayed.

For more information about enabling your iOS to provide position data, please read this article.
