Fix the dash onto the windshield, then insert the memory card. Choose the wiring route according to the vehicle's design, and connect the power to start using it. You can view the content being recorded. The folder contains many previously saved videos, which will be automatically cleared after a certain period.

The operation of the 3 Series factory-installed dash cam is actually quite simple. I've been driving this car for two years and use it daily for my commute. After starting the car, it automatically begins recording around the rearview mirror without needing to press any buttons. To view the live feed, just tap the dash cam icon on the central control screen, and it immediately displays the current road conditions. Recorded videos are stored on the TF card in the glove compartment. To find specific footage, enter the video playback menu and filter by date or time. A particularly useful feature is the automatic collision lock—for example, during sudden braking, the system saves that segment separately to prevent overwriting. I make sure to format the memory card weekly, which takes just seconds via the car's system, ensuring ample storage space and smooth operation. Remember not to connect the dash cam to your phone via Bluetooth, as it can interfere with the signal.

The operation of the 3 Series' original dashcam mainly involves three steps. After the vehicle starts, it automatically enters standby mode, and begins loop recording the moment the ignition is turned on, with a green light flashing on the dashboard as a prompt. For manual operation, there's a quick-access button in the drop-down menu on the central control screen; tapping the red recording icon starts the recording. In emergencies, there's a silver physical button on the left side of the steering wheel—holding it down for 2 seconds immediately locks the current video to prevent overwriting. To review videos, enter the 'Trip Data' section in the central control system, where you can swipe left or right to select date segments, and even directly export them to the mobile app for backup. Daily maintenance is straightforward: occasionally check if the lens is obstructed by dust, and it's recommended to use a high-speed memory card with a capacity of 64GB or more. Remember not to format the card immediately after exposure to direct sunlight, as high temperatures can easily damage it.

I usually just start the car and go, and the factory-installed dashcam automatically starts working—just look for the red light near the rearview mirror to confirm it's on. When parking and turning off the engine, it continues recording for an additional two minutes before shutting down, requiring no manual operation before locking the car. If you need to save a video, such as after witnessing a traffic accident, simply press the physical button with the camera icon on the center console. The easiest way to retrieve videos is via smartphone: first connect to the car's WiFi, then open the BMW Drive Recorder app—videos will automatically sync to your phone's gallery. Remember to tap the small lock icon on important videos to prevent accidental deletion. For regular maintenance, check that the small black box on the windshield isn't obstructed by leaves, and replace the memory card every six months to extend its lifespan.

The core feature of the 3 Series factory-installed dashcam is its deep integration with the vehicle's infotainment system. It starts recording automatically upon vehicle ignition without any manual operation. The system captures synchronized footage via dual front and rear cameras, ensuring clear video even in rainy or foggy conditions without glare interference. Its most intelligent feature is ADAS integration – for instance, when automatic braking is triggered or airbags deploy, the dashcam proactively saves 20 seconds of high-definition footage before and after the incident. Besides viewing videos on the central control screen, users can access cloud services – emergency event videos are automatically uploaded to the mobile app as evidence. For temporary roadside monitoring, long-pressing the vehicle's anti-theft button activates standby recording. Important note: avoid aftermarket wiring modifications as the factory power supply is more stable; using charging ports for other devices may cause voltage fluctuations.

For the genuine dash cam, focus on four key points. The installation position is inside the interior rearview mirror base, and it automatically powers on and starts recording when the vehicle is started, with a red indicator light on the dashboard showing its status. The default recording setting is 1080P resolution; to switch to 4K, you need to manually select it in the infotainment screen settings menu, but this will take up more storage space. The emergency event lock is super useful—press the star button on the left side of the steering wheel when you see a special situation, and it automatically saves the current video with 15 seconds before and after. For maintenance, it's recommended to format the memory card once a month in the vehicle's system, with the formatting option located in the secondary menu of the dash cam app. A special note: don’t let any shops other than BMW dealerships touch the wiring, as it may affect the dash cam's warranty policy.
