Garmin began rolling out Garmin Express v4.3.0 for the PC today. If you would like to upgrade to the latest version, Check for Updates to Express on the Settings page within the Express application. This version includes the following changes:
•No more losing activity data when switching between Garmin devices! If you’re using multiple activity tracking devices from Garmin, we now consolidate your Steps, Calories, Distance (from steps), Floors Climbed and Intensity minutes data using TrueUp.
•Fixed an issue where map installations to the computer were not displaying progress.
