Using the Constant Power Cable with a Garmin Dash Cam

The Constant Power Cable will plug into a vehicle's OBD-II port to provide constant power to up to two compatible Garmin Dash Cams. This will provide power to the Garmin Dash Cams for a time you specify even when the vehicle is parked and turned off.

See the image below for an example of what the OBD-II port looks like. This is only a sample picture. Consult your vehicle owner's manual for the location of your OBD-II port.

The Constant Power Cable is Compatible With Most Passenger Vehicles

  • Not compatible with commercial vehicles with a J1939 connector
  • Compatible with Voltage input from 12 to 16 V
    • Not compatible with 24 V systems

The Constant Power Cable has a Time Switch to Set the Length of Time the Cable Continues to Supply Power After you Exit the Vehicle

  • The time on the Constant Power Cable is set by a physical switch located on the part that connects to the OBD-II port

 

  • Select the 10 minute option if you want the Garmin Dash Cam to turn off after that time and remain off until the Constant Power Cable detects disturbance.
  • Select the 24 hours or Always On option if you want the Garmin Dash Cam to operate continuously while the vehicle is parked.
  • This timer restarts whenever impact or physical motion is detected.
    • Examples include: someone bumps the vehicle, opening/closing the vehicle door, vehicle is being driven, strong winds.
  • The timer will also restart if it detects the engine is running.
    • Not all vehicles support this feature.

The Constant Power Cable Will Protect the Battery by Shutting Down After 10 Minutes if it Detects the Battery is Low (Less Than 12V).

  • The Constant Power Cable will not turn back on until the power levels are restored.
  • Starting the vehicle and allowing it to charge the battery for a few minutes should help restore power to the Constant Power Cable.

Understanding The LED Activity Status on the Constant Power Cable

  • Flashing Red - The timer has expired, and the Constant Power Cable is no longer supplying power to the connected dash cam or navigation devices.
  • Off - The Constant Power Cable is receiving less than 12 V of power. The low battery protection feature turns off the Constant Power cable to protect the vehicle battery.
