Intended use and fitment for BMW Z4 E85/E86

This BMW interior rearview mirror is a rearview mirror designed for installation in the cabin of the Z4 E85 and E86 models. The design is adapted to the factory mounting, allowing the element to integrate seamlessly with the headliner, center console, and other interior components.

The vehicle's rear-mounted location means it's mounted in the center of the windshield, oriented to look out behind the vehicle. This solution ensures an adequate field of vision and adheres to BMW's factory safety and ergonomics standards.

EC, LED functionality and radio system integration

The mirror is equipped with functions that increase the comfort of everyday use:

• EC technology – electrochromic dimming reduces glare from the lights of vehicles behind you, improving driving comfort after dark.
• LED elements – integrated LED lighting provides even, functional illumination of selected interior zones, making it easier to use the cabin in the dark.
• 433 MHz radio signal support – the mirror is designed to work with vehicle systems using this frequency, allowing for consistent operation with factory BMW electronics.

This combination of functions makes the mirror not just a simple optical element, but part of the comfort and safety system in the BMW Z4.

The item is offered in used condition. Many BMW Z4 owners find it a good compromise between cost and functionality – retaining factory design and compatibility while reducing the cost compared to a new component.
