To optimize video quality on the Garmin DriveAssist 51, you should adjust the following settings:
Video Resolution
Set the video resolution to the highest available setting. This can be found in the Dash Cam Settings menu under "Video Resolution"[3]. Higher resolutions will provide better video quality, but may result in larger file sizes.
Memory Card
Use a high-quality memory card with a speed rating of class 10 or higher. A slower memory card may not be able to write data quickly enough, resulting in choppy or incomplete video recordings[1][4]. Replace the memory card if you encounter any errors.
Data Overlay
Enable the "Data Overlay" setting in the Dash Cam Settings menu to include date, time, location, and speed information in the recorded video[3]. This can provide useful context but may slightly reduce video quality.
Record Audio
Decide whether to enable or disable audio recording based on your preferences. Audio recording is enabled by default but can be turned off in the Dash Cam Settings menu[3].
By optimizing these settings, you can help ensure the best possible video quality from your Garmin DriveAssist 51 dash cam. Remember to also keep your device's firmware up-to-date for any software improvements[1].
