Constant Power Cable for Garmin Dash Cam 46-67W - OBD-II Parking Power

In this review the focus is the 010-12530-23 constant power cable designed to keep compatible Garmin dash cams recording when a vehicle is parked. The cable is aimed at drivers who need reliable parking mode or continuous recording without tapping into the vehicle battery manually. Its single biggest selling point is the direct OBD-II connection that provides a constant power supply and three timing modes, which simplifies installation and avoids cutting into the car's wiring. For owners of supported Garmin models this is a practical, plug-and-play option.

Key Features

• Wide device compatibility: Works with Garmin Dash Cam 46, 47, 56, 57, 66W, 67W, Live, Mini, Mini 2, and Tandem so owners of those models can use a single accessory.
• Constant power supply: Provides continuous power to the dash cam even when the vehicle is parked and turned off, enabling parking mode recording.
• Direct OBD-II connection: Plugs straight into the vehicle's OBD-II port for a plug-and-play setup without splicing into the car electrical system.
• Dual USB Type A inputs: Lets users power two devices at once, useful for a secondary camera or an accessory such as a phone charger.
• Timing options: Offers three operating modes - 10 minutes, 24 hours, and always-on - so users can tailor power to their needs and conserve battery when required.
• Passenger vehicle fit: Designed to fit most passenger vehicles; it is not intended for commercial vehicles with a J1939 connector.

Who It's For

The cable suits drivers who own any of the listed Garmin dash cam models and want a simple, non-invasive way to enable parking mode or continuous recording. It is especially useful for commuters, rideshare drivers with personal vehicles, and owners who prefer an out-of-the-box install without running wires behind trim panels.

Those who should look elsewhere include owners of commercial vehicles that use a J1939 OBD connector and anyone who wants a hardwired kit that hides cabling behind the dash; this product relies on the vehicle's OBD-II port and leaves the adapter visible near that socket.

Pros & Cons

Pros

• Direct OBD-II plug-in makes installation quick and avoids cutting factory wiring.
• Provides true constant power for parking mode and uninterrupted recording.
• Dual USB Type A outputs add flexibility to power a second device or accessory.

Cons

• Not suitable for commercial vehicles with a J1939 connector, limiting use in some fleets.
• The OBD-II connection means the dongle remains near the port and may be more visible than a hidden hardwire kit.
