AGW – Audio Gateway Control – N93/1

The Audio Gateway Control (AGW) in a Mercedes-Benz is critical to the vehicle’s audio system. It acts as the central control unit for the audio system and manages various functions, such as radio reception, CD and DVD playback, Bluetooth connectivity, and phone integration.

The AGW is responsible for processing the audio signals from various sources and distributing them to the appropriate speakers in the vehicle. It also controls the volume and equalization settings and provides inputs for the steering wheel controls and other interfaces.

If the AGW in a Mercedes-Benz becomes damaged or malfunctions, it can result in issues such as no sound, distorted sound, or the inability to connect to Bluetooth or other audio devices. In such cases, replacing the AGW can help restore the audio system’s functionality.

AGW stands for Audio Gateway Control unit N93/1. It is located on the left (driver) side inside the trunk.
