Dongar adapters allow you to quickly create a power source for your USB-powered dash cam, radar detector, or any other USB-powered gadget by harnessing the power already flowing through your vehicle. Simply unplug the power source in the console located directly above and behind the rearview mirror and replace it with the adapter to power both your mirror and your dash cam or other USB device. Your result: one of the easiest, cleanest installs possible – no hardwiring, no time spent routing and hiding wires in your vehicle, and no distracting wires hanging across your windshield. This 3-Pin Key Way 1 Dongar adapter is compatible with select Porsche, BMW, and Toyota vehicles, including the Porsche 718 & 981 Cayman/Boxster (with auto-dimming rearview mirrors, various years), Porsche 991 and 911 (with auto-dimming rearview mirrors), BMW 530e (2020), Toyota Supra (2019+), and more. For more information, please see compatibility charts. Please note that an auto-dimming mirror or powered mirror is required. If your vehicle is not listed, you can verify compatibility by assessing the pins in your rearview mirror port or by contacting Dongar support. Please verify fit before purchasing. This 3-Pin Key Way 1 Dongar adapter features a pass through design with a built-in 12V to 5V USB converter.
