Blind Spot Detection Radar Warning System for BMW 4 Series 2013-2020 with Dual MmWave Radar Sensors

Upgrade your BMW 4 Series with a dedicated Blind Spot Detection Radar Warning System designed for 2013–2020 models. This safety-enhancing module uses two mmwave radars mounted on the rear bumper to monitor the blind spots and detect moving objects within a 3–10 meter range behind the vehicle. When danger is detected, LED indicators light up and an audible alert sounds, while the corresponding side turn signal can flash to warn other drivers of your lane-change intent. The result is more confident, safer lane changes and easier parking in busy traffic.

Two 24G/72G Hz mmwave radars provide reliable detection across a wide speed range, and you can choose from two installation styles: a lens-display setup with the prompt light on the lens, or an in-car display that shows warnings on the triangular window inside the car. The system supports BMW 4 Series F32 F33 F36 M4 2013–2020 and can be customized for other models by sending your original mirrors to our factory so engineers tailor the laser warning light pattern to match your mirrors—the price stays the same; you simply cover shipping and any applicable customs duties.

Two mainstream types

• Lens display: prompt light installed on the lens for a clean, integrated look.
• In-car display: warning light shown inside the car on the triangular window area for quick visibility.

LCA lane change assistance, BSD blind monitoring system, AOA Active Overtaking Warning, B-pillar blind spot following warning, RCTA reverse crossing warning, and optional DOW door opening warning give you a comprehensive protection suite for every maneuver—from changing lanes on the highway to backing out of a crowded driveway.

Installation and calibration are straightforward but precise. Please note that radar signals do not penetrate metal and can be interfered with by fluorescent lighting. Before installation, confirm the following: the rear bumper is plastic, there is no metal interference directly in front of the radar sensor (signal emission surface), and the radar sensor is not facing a fluorescent lamp.

Benefits & Tips

• Choose the display option that fits your preference—lens-mounted LEDs for a subtle look or an in-car display for direct notification.
