Mercedes-Benz Antenna Booster / Amplifier 1668201089 — a genuine used OEM part. This left-rear antenna module boosts signal reception for the vehicle's radio and navigation systems. A common failure symptom is weak or intermittent radio reception, especially in the rear of the vehicle, as the amplifier degrades over time.
