What should I do when I play the video through other apps, the audio is not synced? There's a 2 to 3 seconds delay.

Please try the below methods:

1. Upgrade the T-box to the 0301 version.
(Please check here to view how to upgrade the T-box firmware.)

2. Go to the Settings.

3. Click Autokit-TBox Settings.

4. Find out Car Settings--Video Definition, change the number to (6), and then return to the home page to see if the delay problem was solved.

5. Return to the home page to see if the delay problem was solved.

(If it still has a delay problem, please try to modify the Video Definition to other numbers.)

After the above methods, if it still didn't work normally, please upload the log and send the file to us.
