Dash Cam for 2025 BMW M2

Camera: VIOFO A229 Pro 4K 2-channel

Hardwire kit: Viofo HK4

MicroSD card: Viofo 512GB

Battery pack: Power Cell 8

When Marcus pulled into his driveway with his brand-new 2025 BMW M2, he had one thought: this car deserves protection. San Diego streets were no joke—tight parking, distracted drivers, and the occasional mystery ding. It was time to add a layer of invisible armor: a Viofo A229 Pro dash cam system.

He reached out to Dash Cams SD, the local pros known for clean, factory-like installs. The job wasn’t just plug-and-play. His setup included the HK4 hardwire kit and a beefy Power Cell 8 external battery—so the cam could stay active 24/7 in parking mode without draining his car’s main battery.

From the moment the tech arrived, the process was seamless. Panels came off with surgical precision. Wires were routed behind factory trim, completely hidden. No rattles. No shortcuts. The dual-channel A229 Pro—with its razor-sharp 4K+2K resolution—was mounted perfectly behind the rearview mirror, stealthy and centered.

Once connected to the Power Cell 8, the system kicked into gear. The BMW M2 was now watching in silence—even when Marcus wasn’t behind the wheel. Hit-and-runs? Caught. Vandalism? Recorded. Peace of mind? Locked in.

He opened the app, checked the live view, and smiled. The install looked OEM. The footage looked cinematic. And he knew: this was worth every penny.
