The Dash comes with a regional base map pre-installed, based on the original purchase location. Up to 11.1GB of maps can be added to the Dash by customizing your map areas through Stages Link app.
From the Dash manager tab on Stages Link mobile app, select Maps, then Add maps to request a new map region. After requesting a region from the Stages Link app, a downloadable file link will be sent via email for you to download and place on your Dash via USB.
To remove a map region, select it from the Maps listing and tap Delete from Dash.
