What should I do if my Garmin DriveAssist 51's video recordings are choppy or incomplete

Use a high-quality memory card with a speed rating of class 10 or higher[1][2]. A slower memory card may not be able to write data quickly enough to keep up with the video recording, resulting in choppy or incomplete footage.

To ensure optimal performance:

1. Check your current memory card's speed class. If it's below class 10, consider replacing it.

2. If you're already using a class 10 card and still experiencing issues, try formatting the card in the device. This can help resolve any file system issues that might be causing problems.

3. Make sure your device's firmware is up to date, as software improvements may address recording issues.

4. If the problem persists after trying these steps, there might be a hardware issue with your device. In this case, contact Garmin support for further assistance or potential warranty service.

Remember that recording quality can also be affected by environmental factors such as extreme temperatures or excessive vibration, so ensure your device is mounted securely and used within its recommended operating conditions.
