What was wrong with the original Garmin Connect website??? I have the latest version of Garmin Express installed, it picks up my 510, I go to Garmin Connect new website to upload and it say No Device detected...download Garmin Express and around and around I go until i switch to classic view and hit the upload button...
1. Ensure that Garmin Express is fully up-to-date. You can check for updates to Express by clicking on the silver Gear in the top right of the application then click on: [Check for Application Updates]. If a new version is available it will automatically download and then you will click on the Install button. - At the time of this reply the version is: 3.2.16.0
2. Open Garmin Express and delete the Edge 510 from [Devices]. 3. Close out Garmin Express and close the Tray icon by right-clicking on it from your System Tray. 4. Follow both links below and preform the actions outlined in the support articles. 5. Download and Install the latest Garmin Communicator plugin via the manual installation method. (See Link Below). 6. Open Garmin Express and re-add the device into the application and input your Garmin Connect login information. 7. Record a new activity on your device. 8. Use Garmin Express to Sync the device to Connect.
