Overview

The Garmin 010-12530-03 is a hardwire power cable that connects a compatible Garmin Dash Cam to a 12 V DC electrical system, keeping the camera powered so Parking Mode can run when the ignition key or helm switch is off.

The harness is 4 m (13 ft) long and uses a right-angled Micro-B USB plug at the camera end, with three bare-wire leads at the other end for connection at a fuse block or switch panel.

On a boat, it is typically used to power a dash cam mounted behind a windscreen or inside the cabin, so the camera can keep watch at the marina without tying up a 12 V accessory outlet.

Key features

• Hardwire feed for Parking Mode using a constant 12 V supply and a switched 12 V accessory/ignition signal.
• Right-angled Micro-B USB connector at the camera end for a tidy run behind trim and headliners.
• 4 m (13 ft) overall length for routing from the mount location to a fuse panel or helm distribution block.
• Color-coded leads: yellow for battery 12 V, red for accessory 12 V, black for ground.
• Compatible with Garmin Dash Cam 45, 46, 47, 55, 56, 57, 65W, 66W, 67W, Live, Mini, Mini 2, and Tandem.

Compatibility and fit

This is the Micro-USB Parking Mode harness. It fits Garmin dash cams that use a Micro-B USB power input on the camera body.

If your camera uses USB-C, this is not the correct cable. Confirm the connector style and exact camera model before ordering, since Garmin offers more than one Parking Mode cable.

Installation and setup

Installation uses three connections: ground (black) to the negative bus, battery 12 V (yellow) to a fused always-on circuit, and accessory 12 V (red) to a circuit that turns on with the ignition key or a dedicated helm switch. Keep the constant-power feed protected by the correct fuse or breaker for the dash cam circuit, and secure the wiring so it cannot chafe or vibrate loose underway.

Route the Micro-USB end to the dash cam, leave enough slack for aiming the camera, and secure the inline module and harness inside the dash, console, or headliner so it will not rattle in chop.

Notes for marine use

This setup is a good match for boaters who want a cleaner installation and continuous dash cam power at the dock, especially when the camera is mounted in a dry, protected interior location. On open helms, plan to keep all connections inside the console and away from washdowns and spray.
