Descripción
OEM reference 6964400. This genuine used [[BMW]] E38 / E39 / E46 / E53 BM54 Audio Radio Module has been removed from a donor vehicle and fully tested before dispatch, providing a reliable OEM replacement for the integrated radio and audio management unit. ¶ The BM54 combines an FM/AM tuner with audio source management, routing signals from the CD changer, cassette, and external inputs to the amplifier and instrument cluster display. It serves as the central audio hub on these BMW platforms, handling source switching, audio signal routing, and display integration. ¶ Common failure symptoms include complete radio signal loss, audio sources not switching correctly, the instrument cluster displaying no radio source information, weak or distorted audio output from the radio, and intermittent audio dropouts across one or more sources. ¶ Verify OEM number 6964400 against your existing BM54 unit before ordering. Professional installation is recommended. ISTA or equivalent BMW diagnostic coding may be required after fitting for full system integration.
