  • Field of View: A wide-angle lens (around 140° to 170°) is ideal to capture as much of the road as possible.
  • Loop Recording: Ensures continuous recording by overwriting old footage when storage is full.
  • Night Vision: Crucial for capturing clear footage in low light or nighttime driving.
  • Parking Mode: Detects motion or impacts while parked and records automatically.
  • GPS Tracking: Records your vehicle’s location and speed for enhanced data logging.
  • Wi-Fi Connectivity: Allows you to view and download footage wirelessly via a smartphone app.

3. Mounting Options and Size

Most dash cams mount to the windshield behind the rearview mirror, ensuring minimal obstruction. Choose a compact model that blends with the interior of your E-Class. Some dash cams offer adhesive mounts, while others use suction cups. Adhesive mounts tend to provide a more secure and permanent installation.

4. Storage and Memory

Check if the dash cam uses microSD cards and the maximum supported capacity. Larger storage allows for longer recording time, which is especially important if you use parking mode regularly.

5. Brand and Warranty

Opt for reputable brands known for quality and reliability. Brands like Garmin, BlackVue, Thinkware, and VIOFO offer models compatible with luxury vehicles. Also, check for warranties and customer support services.

Preparation Before Installation

Proper preparation is crucial for a smooth dash cam installation. Follow these steps before you begin:

  • Park Safely: Ensure your vehicle is parked on a flat surface, engage the parking brake, and turn off the engine.
  • Gather Tools and Materials: You will need a trim removal tool or plastic pry tool, micro USB or power cable (usually included with the dash cam), adhesive mounts or suction cup, cable clips or zip ties, and optionally a fuse tap kit if hardwiring.
  • Review the Manual: Read the dash cam’s user manual thoroughly to understand specific installation guidelines, wiring diagrams, and safety precautions.
  • Check Your Vehicle’s Fuse Box: Locate the fuse box in your E-Class, which is typically found under the dashboard or in the engine compartment, to prepare for a potential hardwire connection.
  • Inspect Interior Trim: Familiarize yourself with how to safely remove or loosen interior panels and headliner trim without damaging clips or interfering with airbags.

Step-by-Step Installation Guide

Installing a dash cam in your 2018 Mercedes-Benz E-Class involves careful placement, cable routing, and power connection. Follow these detailed steps to ensure a professional and secure installation.

Step 1: Position the Dash Cam

The ideal location for mounting your dash cam is behind the rearview mirror on the windshield. This placement:

  • Minimizes obstruction of your view while driving.
  • Allows the camera to capture a clear, forward-facing view of the road.
  • Keeps the device discreet and less prone to tampering.

Before attaching the mount, clean the windshield thoroughly with glass cleaner to ensure strong adhesion. Use a microfiber cloth to avoid streaks.

Step 2: Mount the Dash Cam

Depending on your dash cam’s mounting system:

  • Adhesive Mount: Peel off the protective backing and press firmly against the windshield. Hold in place for at least 30 seconds to ensure full adhesion.
  • Suction Cup Mount: Attach the suction cup to the windshield and lock it in place by pressing or twisting the lever. Make sure the suction is strong enough to hold the camera securely.

Adjust the camera angle to ensure it has an unobstructed view of the road ahead, slightly tilted to avoid glare from the dashboard or hood.

Step 3: Route the Power Cable

Proper cable management is vital for a neat installation and to avoid interference with vehicle systems. Follow these guidelines:

  • Run the power cable along the edge of the windshield, tucking it behind the headliner.
  • Use a trim removal tool to gently loosen the headliner and tuck the cable underneath.
  • Continue routing the cable down the A-pillar (driver’s side preferred), being careful not to obstruct airbags or wiring harnesses.
  • Secure the cable with cable clips or zip ties to prevent sagging or interference with pedals and controls.

Step 4: Connect the Power Source

There are two common ways to power your dash cam in the 2018 E-Class:

Cigarette Lighter Adapter

Plug the dash cam’s power adapter into the 12V cigarette lighter socket. This is the simplest method but may leave visible cables.

Hardwiring to the Fuse Box

For a seamless and professional look, hardwire the dash cam to the fuse box using a fuse tap kit:

  • Locate a suitable fuse slot that provides switched power (turns on and off with ignition) to avoid draining the battery.
  • Use a multimeter to confirm the fuse’s function if unsure.
  • Install the fuse tap adapter onto the fuse and connect your dash cam’s power cable.
  • Connect the ground wire to a suitable chassis ground point.
  • Secure all wiring away from moving parts and airbags.

Hardwiring keeps the installation tidy and allows features like parking mode to function without the need to plug and unplug the device.

Step 5: Test Your Dash Cam

Once the dash cam is mounted and powered, it’s important to verify that it operates correctly:

  • Turn on your vehicle’s ignition; the dash cam should power on automatically.
  • Check the camera’s display or app interface to confirm it’s recording.
  • Adjust the camera angle if needed to ensure the road ahead is fully visible.
  • Review some test footage to verify video quality and audio recording.
  • Test additional features such as GPS tracking, Wi-Fi connectivity, or parking mode.

If the dash cam does not power on or record correctly, revisit your wiring connections and consult the user manual.

Additional Installation Tips for Your Mercedes-Benz E-Class
