What this part does

The Antenna Amplifier receives and boosts radio frequency signals from the integrated rear window antennas before routing them to the infotainment head unit. It is typically mounted underneath the rear roof lining, positioned directly above or alongside the rear glass. This module actively switches between different antenna elements in the glass to maintain the strongest possible AM, FM, and remote key fob reception. When this component fails, the vehicle will usually experience heavy radio static, dropped stations, or a severely reduced range when using the keyless entry remote.

Before you order

• You must match the OEM number 932572302 exactly to the sticker on your original unit. BMW uses multiple antenna amplifiers operating on different frequencies depending on the vehicle's specific option codes and regional market.
• Accessing this part requires carefully lowering the rear section of the interior headliner. Avoid creasing the headliner board during removal.
• Before plugging the replacement module in, inspect the coaxial cables and harness connectors in the vehicle it came from for signs of water ingress, which is a common cause of failure for roof-mounted electronics.
