Why Upgrade Your BMW 3 Series G20's Dash Cam?
Many BMW 3 Series G20 owners experience issues with their factory-installed dash cams. Over time, these units can suffer from recording failures and playback problems, leading to a loss of crucial footage. While official BMW service centers may charge upwards of 500,000 Korean Won for a replacement, the performance of aftermarket dash cams has significantly improved, offering a compelling upgrade path for many owners. This particular owner sought to enhance their vehicle's security beyond a simple replacement, aiming for comprehensive 360-degree coverage.
From 2-Channel to 4-Channel: Eliminating Blind Spots
To combat frequent 'door ding' incidents, the owner desired a system that extended coverage beyond the standard front and rear. The goal was a true 360-degree monitoring system, capturing footage from the front, rear, and both sides of the vehicle. The chosen solution was the I-Navi Z9500 dash cam, which, when paired with an optional mixing box, can support up to five channels. For this BMW 3 Series G20, a 4-channel setup was implemented, providing simultaneous recording from all four directions.
A notable difference between factory and aftermarket dash cams is the rear camera size. While the OEM unit is larger, offering good visibility, it can obstruct the driver's view in the rearview mirror. The I-Navi Z9500's rear camera is significantly more compact, minimizing any visual interference.
Advanced Features: Connected Pro Plus and Auxiliary Battery
A key feature of this installation is the Connected Pro Plus functionality. This system alerts the driver's smartphone instantly upon detecting a vehicle impact and transmits pre- and post-impact video clips. This ensures that even parking incidents are recorded and accessible. To support this continuous monitoring and notification capability without draining the car's main battery, an auxiliary battery is essential. The Carecell CZ016 auxiliary battery was selected for its high durability and reliability. Its LED display clearly shows remaining capacity, protecting the vehicle's primary battery during extended parking periods. The cost-effectiveness of an auxiliary battery compared to potential battery drain issues makes it a wise investment.
Side Camera Installation: Ending Door Ding Worries
The strategic placement of side cameras is crucial for a 4-channel dash cam system. Understanding the common locations for door dings, the cameras were positioned to capture any such incidents effectively. This comprehensive coverage ensures that the owner has clear evidence should any damage occur to the vehicle's sides.
Installation Process:
- Vehicle Preparation: The interior trim panels around the windshield, rear window, and side pillars are carefully removed to allow for clean wire routing.
- Camera Mounting: The front, rear, and two side cameras are securely mounted in their optimal positions, ensuring clear fields of view.
- Wiring and Connection: All camera cables are routed discreetly through the vehicle's headliner and pillars, connecting to the main dash cam unit and the mixing box. The auxiliary battery is installed and wired to the dash cam.
- System Configuration: The dash cam unit is powered on, and its settings are configured, including the 4-channel recording mode and Connected Pro Plus alerts.
- Final Checks: All trim panels are reinstalled, and a test recording is performed to verify that all cameras are functioning correctly and the system is operational.
