How often does the built-in dash cam in Mercedes-Benz overwrite recordings?

Mercedes-Benz dash cam recording duration depends on the set resolution and memory card capacity, typically ranging from 3 days to a week. Time options: Dash cam loop recording settings usually offer different time intervals such as 1 minute, 2 minutes, 3 minutes, 5 minutes, and 10 minutes. After completing one segment, it automatically moves to the next. When setting the loop duration, avoid choosing intervals that are too short or too long. Function: A dash cam is a device that records images, sounds, and other relevant information during vehicle operation. After installation, it can document the entire driving process through video and audio, providing evidence for traffic accidents.
The built-in dashcam in Mercedes-Benz doesn't have a fixed overwrite time. It typically records in a loop, automatically overwriting the oldest video clips once the storage is full. How often it overwrites depends on the memory card size and recording quality. For example, using a 64GB card for HD recording might fill up after just a few days of driving, then start overwriting old footage. From my own driving experience, I've noticed that important events can easily be lost if you don't set longer cycles. I recommend checking your vehicle manual or going into the settings menu to adjust the overwrite interval. Choosing a larger memory card or developing a backup habit would be safer.
When driving a Mercedes, there's no standard time for the dashcam to overwrite old footage—it only deletes old recordings to make space for new ones when the memory card is full. With a regular card, overwriting happens quite quickly; often just a few hours of driving fills it up, and old recordings are gone. This depends on the card's capacity and the recording quality—higher resolution consumes more space, leading to faster overwrites. Later, I learned to manually extend the overwrite cycle or schedule file backups in the car's menu to avoid losing data.
