Garmin Express™ software is a computer application that interacts with various Garmin® products in order to sync data, download software updates, and update maps either preloaded to some devices or maps that have been purchased separately. See What is Garmin Express? for more information. To use Garmin Express the device needs to be connected to the computer using the USB charging cable or an ANT+ stick. If the application is installed, Garmin Express will launch and connect with the external drive.
NOTE: Garmin Express is not compatible with phones or tablets and requires a personal Windows or Mac computer to use. An ANT Stick is required to use Garmin Express with the following watches: Forerunner® 310XT/405/405CX/410/610/910XT, Garmin Swim™, vívofit® 1/2/3/4, and vívomove®.
