Setup
1. Inserting the Memory Card
Locate the MicroSD card slot on the side of the mirror dash cam. Insert a MicroSD card (Class 10 or higher, up to 128GB, not included) with the contacts facing the screen until it clicks into place. Ensure the card is formatted before first use (refer to 'Operating Instructions - Formatting the Memory Card').
2. Installing the Mirror Dash Cam
- Secure the mirror dash cam over your vehicle's existing rearview mirror using the provided rubber straps. Ensure it is firmly attached and does not obstruct your view.
- Connect the car charger to the dash cam's power input port and plug the other end into your vehicle's cigarette lighter socket.
- Route the power cable neatly along the windshield trim and dashboard to avoid interference with driving.

3. Installing the Rear Camera
- Choose a suitable location for the rear camera, typically above the license plate or on the rear window. Clean the surface thoroughly before mounting.
- Secure the rear camera using the provided adhesive or screws.
- Connect the rear camera cable to the rear camera.
- Route the 32.8ft (10m) rear camera cable from the rear of the vehicle to the front dash cam. Ensure the cable is tucked away safely, avoiding sharp edges or moving parts.
- Connect the rear camera cable to the designated port on the mirror dash cam.
- For backup assist functionality, connect the red wire from the rear camera cable to your vehicle's reverse light positive wire. This enables the parking guidelines to appear when reversing.

4. Hardwire Kit Installation (for 24-Hour Monitoring)
The included hardwire kit allows for continuous power supply to the dash cam, enabling parking monitoring features even when the vehicle is off. Professional installation is recommended for the hardwire kit.
- Connect the ACC wire to a fuse that is only powered when the ignition is on.
- Connect the B+ wire to a constant power fuse (always on).
- Connect the GND wire to a metal part of the vehicle chassis for grounding.
The hardwire kit includes voltage protection to prevent draining your car battery. It will automatically cut off power if the voltage drops below 11.6V (for 12V systems) or 23.5V (for 24V systems).
