Setup and Installation
The DoHonest V25 system is designed for easy wireless installation.
Step 1: Install the Camera
Locate a suitable mounting position for the camera, typically near the license plate. Connect the camera's power wire to your vehicle's backup light wire. Ensure correct polarity (positive to positive, negative to negative). T-tap connectors can be used for easy connection. License plate lights and tail lights can also be used as power sources if preferred.

DIY Guide Lines
The system allows for customization of parking guide lines. You can adjust the width (W), move them up or down (H), and shift them left or right (M) to suit your vehicle and parking preferences. Refer to the monitor's menu for these settings.

The monitor supports up to two cameras, allowing for full-screen display or split-screen monitoring of both cameras simultaneously. An additional camera (not included) can be added for expanded coverage, such as an RV backup camera.
