Hello! I've reviewed the instructions for the Garmin Constant Power Cable. This device seems to provide a convenient way to keep your dash cam powered even when your vehicle is off using your vehicle's OBD II port. It also has a timer to manage power and several other safety features. I'm ready to answer any questions you might have about this device and its usage!

Where is the OBD II port usually located?
What does the red status LED indicate?
How can I set the duration for which the device will supply power?
What should I do if I notice any change in engine performance after connecting the device?
