I am trying to enable the Audio prompt for turn by turn navigation in my Garmin connect App IOS 12.1. My device is agarmin Edge 820. I go to Garmin connect > Garmin Device > Settings > Device Settings > Audio Prompt > Turn ON the Turn by Turn navigation alert > go back and Sync to save the settings.
Error : After sync the turn by turn navigation alert switch is automatically getting switched OFF. I am fully blocked. Appreciate any help or help raising a defect.
