About this part
Also known as

Aerial Control Module
Diversity Module
What this part does
The Antenna Control Module processes and amplifies radio frequency signals received by the antenna traces embedded in the rear glass or roof area. It actively manages the diversity system, constantly analyzing multiple antenna inputs to send the strongest, clearest signal to the vehicle's infotainment, navigation, and comfort access systems. When this module fails, common symptoms include static or complete loss of AM/FM radio reception, intermittent GPS signal drops, or a sudden decrease in the operating range of the remote key fob.

Before you order
BMW uses several different variations of this module depending on the specific equipment ordered with the car, such as satellite radio, digital tuners, or specific comfort access frequencies. You must match the exact OEM number to your original unit. Water intrusion from compromised rear window or roof seals is a frequent cause of failure for these modules; verify the mounting area is completely dry and correct any leaks before installing the replacement part to prevent a repeat failure.
