Route Recalculates After Being Imported into the Tread App
When a GPX file containing a route is uploaded to the Tread® app, and is viewed from the Saved menu for the first time, the route will be recalculated. After the route is recalculated, the route may change in both the Tread app and the device after they sync. This can be corrected by adding shaping points to the route. To add shaping points to the route, see Using the Route Planner in the Tread App.
NOTE: When using the zūmo® XT2 GPS navigator, Tread® GPS Navigator, and all models in the Tread® series, it is recommended to use the Tread app for creating waypoints, routes, and tracks.
