### Technical characteristics of the BMW E81 E87 rearview mirror
This mirror is **a rearview mirror** designed specifically for **BMW** vehicles. EC (electrochromatic) technology automatically dims the mirror glass in strong rear light, improving comfort and safety when driving at night.

### Functionality and vehicle integration
The rearview mirror with EC/LED/Radio function was designed to work with the BMW factory electrical system. This allows:

This combination of functions makes the mirror not just a simple optical element, but part of a broader comfort and safety system in the cabin of the BMW 1 Series.
