2. Einrichtung und Installation
2.1 Installation eines Spiegelmonitors
To install the VOM74MM monitor, first remove the existing rearview mirror. Access to the mirror mount may require prying open the panel behind the mirror. Once the old mirror is removed, the new VOM74MM monitor can be installed onto the existing mount. Ensure all connections are secure before re-clipping any panels.

2.2 Stromanschluss
The monitor requires a 12VDC power source. The easiest location to tap into power is typically the vehicle's fuse box, often found near the driver's seat. Identify a suitable ignition-powered fuse (e.g., Fuse #24 for 5A ignition power, as indicated in some vehicle models) and use a fuse tap to connect the monitor's power wire. This ensures the monitor powers on and off with the vehicle's ignition.

2.3 Installation der Rückfahrkamera
For optimal rear visibility, mount the backup camera on the vehicle's back cap. Many back caps are hollow, allowing for easy routing of the camera cable. Secure the camera using the provided mounting bracket and screws. Ensure the rubber grommet on the camera cable is properly seated in the drilled hole to maintain a weather-tight seal. Route the cable along the vehicle's frame rail and into the cab, connecting it to one of the monitor's camera inputs.
