1 Answers
The USB port under the Haval F7x rearview mirror is primarily used to power a dash cam, but it can also supply power or charge other USB devices. Below is some relevant information: A dash cam is a device that records images, sounds, and other related data during vehicle operation. Dash cams are mainly divided into two categories: portable dash cams and aftermarket integrated DVD dash cams. Here are the details: 1. Portable dash cams can be further classified into rearview mirror dash cams and data dash cams. These types of dash cams offer advantages such as good concealment, easy installation, detachability, low cost, and simple operation. 2. Aftermarket integrated DVD dash cams are usually vehicle-specific and can be divided into pre-installed and post-installed types. Installing these dash cams is more costly and challenging, but they help maintain the aesthetics of the car's interior. Additionally, some luxury models come with pre-installed dash cams from the factory.
