The Garmin Dash Cam 66W is a mid-range dash cam offering a balance of features and affordability. This review will dissect its strengths, weaknesses, and who it might best suit to help you decide if it’s the right dash cam for you.


  • Sharp Video Quality: The 66W captures clear 1080p video footage at 60 fps, providing smooth playback and capturing details like license plates even during fast-paced situations. It also boasts HDR (High Dynamic Range) for improved image clarity in scenes with contrasting light conditions.
  • Wide Viewing Angle: The 180-degree wide-angle lens captures a comprehensive view of the road ahead, including adjacent lanes and potential blind spots. This can be crucial for capturing the full picture in case of an accident.
  • Driver Assistance Features: The 66W offers some helpful driver assistance features like forward collision warnings and lane departure warnings. While not a substitute for safe driving, these alerts can provide an extra layer of awareness on the road.
  • Compact Design: The 66W maintains a discreet profile that minimizes windshield obstruction. This is a plus for drivers who prefer a less noticeable dash cam.
  • Voice Control: For hands-free operation, the 66W allows voice commands to start/stop recording, capture stills, and save videos.


  • Night Vision Performance: While HDR helps in some low-light scenarios, night time video quality can be a mixed bag. Reviews mention details like license plates becoming less legible in darker conditions.
  • Limited Storage Options: The 66W relies on microSD cards for storage (not included). While expandable, it requires users to manage storage space and potentially format cards periodically to ensure continuous recording.
  • App Dependence: Certain features like accessing saved footage and changing settings require the Garmin Drive app on your smartphone. This might be inconvenient for those who prefer a standalone solution.
  • Proprietary Power Cable: The 66W uses a Garmin-specific power cable, which can be a nuisance if it gets lost or damaged, as replacements might be less readily available compared to standard USB cables.


The Garmin Dash Cam 66W is a decent option for drivers seeking a balance between price and features. It delivers good video quality in well-lit conditions, offers a wide viewing angle, and includes some helpful driver assistance features. The compact design and voice control are convenient additions.
