Description
OEM numbers 84106945425 and 6945425-02, BMW, BMW E46 / E53 / E81 / E87 / E85 / E86, phone antenna diplexer and booster module, genuine used and tested.
This module performs two functions: the diplexer separates or combines multiple frequency bands on a single antenna cable, allowing the telephone system and radio to share the same antenna, while the integrated booster amplifies the cellular signal to improve hands-free telephone reception quality within the vehicle.
Failure of this module may result in poor or absent mobile phone signal within the car, call quality degrading when using the hands-free system, and in some cases degraded radio reception if the antenna path is shared.
Supplied in good used condition, verified against OEM numbers 84106945425 and 6945425-02 before dispatch. Fits BMW E46, E53, E81, E87, E85, and E86. Professional installation is recommended. 14-day return policy applies.
Returns accepted only for genuine faults — faulty on arrival, not as described, or wrong part supplied — requested within 14 days, with all 3 anti-tamper stickers intact. No returns for change of mind, incorrect installation, coding/programming, or buyer compatibility errors; checking compatibility (OEM number, firmware, vehicle) is the buyer’s responsibility.
