If your Ford Sync is not playing music, it could be due to a variety of factors. First, check to make sure that your phone is properly connected to the system. If it is, then the problem may be with the Sync itself. There are a few things you can try to troubleshoot the issue:
1. Restart your Ford Sync system. This may sound like a simple solution, but sometimes restarting the system can fix minor glitches that may be causing the audio playback issue.
2. Check for updates. If there are any available updates for your Sync system, install them as soon as possible. These updates often contain bug fixes that could resolve the issue you're experiencing.
3. Delete and reinstall any apps you're using on your phone that connect to Sync (e.g., Pandora, Spotify, iHeartRadio). Sometimes these apps can cause problems with Sync that can lead to audio playback issues. Uninstalling and then reinstalling them may help resolve the issue.
4.. Perform a master reset of your Ford Sync system by following these instructions: https://support-en-usa1cbd0f8606fbf27b72db5d00ba0652b7acd2291cbd0f8606fb... .
