　　Rearview mirror navigation is a combination of rearview mirror installation, generally integrating functions such as driving record, navigation, cloud dog, etc. Compared to the original rearview mirror, it has a significant increase in mirror area, making driving more convenient.

　　Advantages and disadvantages of rearview mirror navigation:

　　It basically does not affect the overall appearance of the car interior, but also increases the visible area of the rearview mirrors. Many of them are made of blue light materials, which can effectively deal with the problem of strong light in the rear car, and the functions are also relatively diverse. However, some products have substandard screen designs, and the use of rearview mirrors is inconvenient. When the screen is on, it is even impossible to observe the situation behind the car.

　　Rear view mirror navigation selection:

　　It is recommended to choose a wide-angle angle between 120 and 140 degrees, as images with too large a wide-angle can easily deform; To improve night vision and achieve zero glare, high-quality lenses with blue mirror ion technology and brightness adjustment function can be selected.
