Intended use and fit for BMW models

This mirror is a rearview mirror designed for installation inside the vehicle, in the rear of the cabin. Its design complies with BMW factory standards, making it easy to install in E87, E90, E60, and X5 E70 series vehicles without requiring any modifications to the mounting or electrical system (provided the vehicle wiring harness is maintained).

The element was designed as an integral part of BMW's comfort and safety systems, so it interacts with the vehicle's equipment in a predictable and stable manner.

Functions: EC, LED, ETC

The mirror is equipped with an electrochromatic EC function, which automatically darkens the glass in strong rear light. This increases nighttime driving comfort, reduces eye fatigue, and improves visibility.

Integrated LED lighting provides even, spot-lit illumination around the center console and tunnel, making it easier to access the cabin's equipment after dark. ETC (Electronic Toll Collection/communication module) compatibility, available in select markets, allows for integration with compatible on-board systems, if the vehicle is equipped with them.

Construction and location on the vehicle

The mirror is designed for mounting in the rear of the vehicle, in the standard location provided by the manufacturer. The design is based on the factory mount, ensuring:

• stable mounting without vibrations while driving,
• proper field of view in accordance with the homologation,
• ergonomic positioning in relation to the driver's seat.

The glass pane has been designed to provide a clear view of the space behind the vehicle, while reducing light reflections thanks to the EC function.

Used condition and the benefits of choosing OEM parts

The mirror offered is in used condition, which means it retains its original design and compatibility with BMW installation while offering an attractive price compared to a new item. The used OEM component is:

• factory fit with headliner and windshield,
• maintaining the original interior aesthetics typical of BMW,
• the possibility of economical repair or restoration of vehicle equipment.

For many users, this is a reasonable compromise between cost and maintaining the character of the car as designed by the manufacturer.

Application in service and interior modernization

The interior mirror with EC, LED, and ETC is suitable both as a replacement part for damaged original components and for interior upgrades in vehicles that are factory-prepared for the appropriate installation. By adhering to BMW standards, it enables:

• restoring the full functionality of the automatic dimming system,
• regaining comfortable LED lighting in the interior,
• maintaining consistency of equipment with the rest of the cockpit.
