Description
OEM number 4B9035501, Audi, Audi A4 B5 / A6 C5 Avant, AM FM GSM roof antenna amplifier base, genuine used and tested.
This roof-mounted antenna base integrates AM, FM radio, and GSM telephone antenna elements with built-in amplification, providing a single combined mounting point for all three signals on the Avant roofline and amplifying each signal before distribution to the relevant head unit or telephone module.
Failure of this unit can cause simultaneous degradation of AM and FM radio reception and mobile telephone signal strength inside the vehicle, as all three antenna feeds are integrated within the same module.
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.
