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.
