Purpose and functions of the mirror

This BMW auto-dimming rearview mirror is designed to be mounted inside the cabin, on the windshield. The integrated auto-dim (EC) function responds to the intensity of light from behind the vehicle, reducing glare and improving driving comfort at night and on the road.

The presence of the EC/Radio function means the mirror works with the vehicle's electrical system and on-board systems, in accordance with BMW's factory specifications for a given generation. This ensures full integration with the vehicle's electronics, without the need for universal solutions or wiring modifications.

Compatibility with BMW models

This mirror is designed for select BMW E65, E90, E63, and E91 models that are factory-installed with an auto-dimming interior mirror. Before purchasing, it's worth verifying compatibility with your specific trim level and vehicle year using the OEM number and interchangeable numbers available in the technical specifications.

Users who want to be sure of the correct component selection will find it helpful to compare the vehicle's equipment configuration (e.g., presence of sensors, comfort modules) and consult with a mechanic or service advisor. If in doubt, you can also seek advice on selecting parts based on the OEM number and vehicle data.

Technical condition and advantages of using a used part

The mirror offered is a used BMW rearview mirror, meaning it comes from a dismantled vehicle. While maintaining technical functionality, these components offer a reasonable compromise between cost and functionality, preserving the original interior appearance and ensuring full compatibility with the vehicle's electrical system.

The key advantages of using an original, used mirror include:

• factory fit to the windshield mounting and electrical harness of a given BMW model,
• visual consistency with the dashboard, headliner and other cockpit elements,
• maintaining the auto dim function and integration with vehicle systems, as configured in the factory.

Assembly and operational aspects

Installing an interior mirror with automatic dimming in most cases comes down to:

• dismantling the old mirror from the holder on the windshield,
• connecting the electrical connector according to the factory wiring harness,
• placing the new element on the mounting foot.

With proper care and the right tools, the operation is relatively simple for an experienced mechanic or auto electrician. Once installed, the mirror automatically interacts with the vehicle's light sensors and electronics, ensuring stable dimming performance during nighttime driving.

How to choose the right mirror by OEM number
