Dashcam Type: OEM Integrated Bmw mini dashcam

⚠️  Power off and power on precautions: Completely turn off the power: remove the car key or turn off the vehicle's "start stop" power supply (if it is a new energy vehicle, please ensure that the dashboard is completely black and the entire vehicle is in a powered off state).

Step 1: Inspect the Vehicle and Prepare the Installation Area

The mainstream installation method for a dedicated car dashcam (hidden dashcam) is to remove the original housing of the rain sensor (rain sensor) or light sensor behind the original rearview mirror without damage, and then replace it with a dedicated dashcam housing with a camera. This' factory replacement 'design has the following core advantages:

No damage to the original car interior: completely inheriting the original car buckle position, without the need for additional punching or adhesive, with high adhesion and not easy to fall off.

Perfect hidden wiring: It is directly hidden behind the rearview mirror and usually uses a dedicated plug-in harness to take power from the inside of the rain sensor, without damaging the car roof and A-pillar trim panel. The appearance is almost identical to the original car when it leaves the factory.

Unbounded driving vision: Perfectly avoiding blind spots in the driver's line of sight, while the lens is positioned in the center of the windshield wiper cleaning area, ensuring the best shooting view.

After installation, it will not affect the automatic wiper function of the original car's rain sensor. The lens angle is usually fixed at the factory and does not require manual adjustment by the driver in the later stage.

Step 2: Remove the Factory Mirror Cover

Using a plastic trim tool, carefully separated the upper and lower mirror shroud sections. The original housing is going to replaced with a custom-designed cover that perfectly matches the factory interior trim. Make sure The clips released safty without damaging any interior components. Keep your original rain sensor housing in case for future re-use.

Step 3:Access the Factory Wiring Connector and Disconnect the Original BMW MINI Cooper Cable

Locate the factory wiring connector behind the rearview mirror housing. Carefully unplug the original BMW MINI Cooper cable from the rain sensor module, making sure not to damage the factory clips or connectors. This allows the OEM dashcam power harness to be installed using a plug-and-play connection without cutting any wires.

Step 4: Connect the Plug-and-Play Power Harness

Connect the Mercylion OEM-style Y-split harness between the original BMW MINI Cooper factory connector and the vehicle wiring. After that, plug the dashcam power cable into the harness to complete the installation without cutting any factory wires.

Step 5: Mount the Dashcam unit

After connecting the power cable, carefully mount the dashcam unit to replace into the original OEM housing place and make sure it is securely positioned.Then reinstall the dashcam cover and make sure all clips are properly locked in place for a clean OEM-style finish.

Step 6: System Testing and Configuration

Insert the SD card to the slot. Now that all trim is restored, cycle the Mini’s ignition to ON (EV ready mode) to boot the Mini Cooper dashcam. The unit will automatically connect to the vehicle’s 12V auxiliary power and broadcast its Wi-Fi hotspot for smartphone pairing. Walk through these critical post-install tests to validate flawless operation:

Automatic startup
Loop recording
WiFi connection
Mobile app pairing
Video playback
Emergency event recording

To activate parking mode, use an OBD power cable or hard-wire to the fuse box.

Final Inspection and Road Test

After installation, I performed a complete inspection and road test to verify recording quality and camera positioning.

The camera delivered excellent visibility with no obstruction to the driver's field of view. Video footage remained clear during both daylight and low-light driving conditions.
