My X3 is equipped with an aftermarket dash cam, and viewing it directly on the mobile app is the most convenient. While driving, just open the app for real-time monitoring. After parking, select the video playback menu, and the videos are automatically sorted by date and time. Emergency recordings are saved in a separate folder, so you can directly retrieve them as evidence in case of a scrape. It's recommended to use a TF card with 128GB or more capacity; otherwise, older emergency recordings will be automatically overwritten when the storage fills up. Here's a tip: use the 5-minute clip mode for playback when you want to watch scenic segments, as it offers much higher clarity than continuous recording. Remember to turn on the parking surveillance feature so the dash cam continues to work even after the car is locked.

The factory-installed dash cam needs to be operated through the vehicle's infotainment system. After starting the car, open the main menu of the infotainment system and look for the 'Applications' or 'My Vehicle' option. Scroll down to find the dash cam icon. Tapping it will display the live feed and video list, with a calendar symbol on the right side of the screen for selecting dates to view. Press the play button to watch recordings in full screen, and you can fast forward or rewind by touching the screen. The latest model supports gesture control—swiping two fingers in different directions switches between front and rear camera views. For knob operation, note that pushing the rotary button to the right confirms your selection. Recordings are automatically saved for 72 hours, so remember to export important clips promptly.

Using a Type-C interface is the most convenient. Look for the USB port with a dashcam icon in the glove box or center console, then connect your phone cable. Open the file manager on your phone, and the dashcam will appear as a removable disk, allowing you to directly copy and view videos on your phone. The new X3 comes with in-car WiFi—connect to the dashcam's hotspot and access the management backend at 192.168.1.1. If playback is laggy on your phone, try switching to the 5GHz band. Emergency videos have filenames ending with '_EV', while loop recordings are marked '_NOR'. When the memory card is full, a yellow warning will pop up on the dashboard—it's best to stop and replace the card then.

When checking recordings with the engine off, pay attention to the power supply. Press the ignition switch twice to power on without starting the engine, and operate after the large screen lights up. During playback, watch the battery indicator—stop viewing if it shows less than 30 minutes of remaining power. To access footage from six months ago, continuously press the 'Last Month' button. Newer infotainment systems with a search box allow direct date entry. The button next to the rain sensor is for manual emergency recording; pressing it will trigger a green indicator light on the dashboard to flash three times. When adjusting recordings from the passenger seat, avoid touching the speed button, as it will automatically switch to live navigation and interrupt playback. Remember to format the memory card every three months.

There are tricks for reviewing footage on long drives. When connected to CarPlay, saying 'Hey Siri, open the dashcam' can wake up the phone app, allowing direct control of playback speed using the steering wheel voice button. Using a USB splitter enables simultaneous phone charging and video playback. For aftermarket dashcams with screens, press the REC button twice to enter playback mode. For important videos, it's recommended to press the emergency recording button three times to prevent overwriting by loop recording. A detail about BMW's factory dashcam: when the speed exceeds 30km/h, playback is forced into picture-in-picture mode for safety. When adjusting night footage, remember to turn off the screen's night mode, or the image will appear gray and unclear.
