I cannot adjust the screen brightness on my device

If your Garmin DriveSmart™ device is not supplied with enough power, the screen does not display at full brightness.

  • Verify your vehicle is turned on and is supplying power to the power outlet.
  • Verify the Garmin DriveSmart device is connected to vehicle power using the included vehicle power cable and the included vehicle power adapter (Mounting Considerations).
