I bought the Garmin constant power cable which plugs into the OBD-II port. The OBD-II port gives constant power, something I didn’t really know or think about. This plug has 2 USB-A ports and has a setting to allow power for 10 minutes, 24 hours or infinite power. I keep it on the 10 minute setting so the camera has power for a few minutes after shutting the truck off. Opening your door will trigger it on. I suspect unlocking your door does the same thing. IMO it’s pricey but it allows me to not have to tap into any existing wires and if we take my wife’s vehicle and want a camera, it’s easy enough to switch over. Plus controlling how long the camera has power is pretty cool.
I also bought the suction cup mount since I didn’t want anything glued to my tinted windshield.
