VERTIX 2 Satellite/GPS Connection Issue
Starting on July 11th, 2022 we are aware of a problem causing the VERTIX 2 to have trouble connecting to satellites. This issue is caused by the most recent download of satellite data downloaded automatically within the COROS app and leads to long delays while trying to establish a new satellite connection.
Solution: To resolve this issue, please adhere to the following steps.
- Manually update satellite data within the COROS app
a. Navigate to the Device page (4th tab on bottom) and select "GPS Satellite Data"
- Allow extra time before any activity for your VERTIX 2 to connect to satellites
- In 1-3 days satellite data will be automatically refreshed, resolving the issue
If none of the above solutions work, please contact support@coros.com, and our team will be more than happy to help.

Failure to properly update the satellite location data
We have noticed a widespread issue causing COROS watches to display the soon-to-be-expired satellite location data message despite recent updates on the COROS app. The team is investigating the issue and expects to provide solutions soon.
Watches with expired satellite data may take up to a few minutes to establish GPS connections. It's highly recommended to wait until the GPS is fully connected before starting outdoor workouts.
Solution: Please go to the COROS app > Device page > GPS Satellite Data to manually update the data.
