How to use the camera under the rearview mirror of Lingpai garage?

Hello, do you want to install rearview mirror and universal ball head, or do you want to install rearview mirror bracket? If you want to install the ball head, you need to open or remove the iron snap ring in the ball head hole in the mirror, and then press the ball head in. Lock the snap ring to promote drying and prevent the bearing from being stored. Note that the snap ring needs to be sleeved at one end of the ball head, otherwise it won't fit in. If you want to install the bracket, you can take a look at a plastic decorative plate on it and then remove the bracket.
