What this part does
The Antenna Control Module (often referred to as the diversity amplifier) is responsible for receiving and processing wireless signals before sending them to the vehicle's main computer systems. Located near the rear window or integrated into the roof antenna array, this unit actively manages inputs from the AM/FM radio, GPS navigation, cellular data connections, and the remote key fob.
Because it continuously evaluates multiple antenna signals to select the strongest one, it ensures clear audio and uninterrupted data links. When this module fails, you will typically experience static or complete loss of radio reception, an inability for the navigation system to lock onto satellites, or a remote key fob that only works when held directly next to the vehicle glass.

Before you order
Match the eleven-digit BMW part number exactly. Antenna modules are highly specific to the vehicle's production date, region, and optional equipment (such as satellite radio or specific cellular bands). Installing a module with a different part number will result in missing frequencies or features.
Before installing the replacement, inspect the wiring harness connectors and the mounting cavity in your vehicle. The most common cause of failure for these units is water ingress from a leaking roof seal or rear window gasket. If the original connections are corroded, they must be cleaned or repaired to prevent the replacement module from shorting out.
