Becker MB Car Bluetooth Adapter - Plug & Play AUX for Becker Radios

Our review of the Becker MB Car Bluetooth Adapter focuses on owners of Becker radios from the mid 1990s to early 2000s who want modern phone and music streaming without cutting wires or replacing the head unit. This adapter installs through the original Becker CD changer port so installation is fast and reversible, and it brings both Bluetooth audio streaming and handsfree calling into older factory systems. The single biggest reason to buy is the clean integration: it preserves the car interior while adding wireless playback and steering wheel control compatibility in many Becker-equipped Mercedes models.

Key Features

• Plug and play installation: Installs via the original Becker CD changer port with no wire cutting, keeping the car interior intact.
• Handsfree calling (HFP): Allows answer and hang up using radio or steering wheel buttons, keeping calls safer while driving.
• Wireless A2DP playback: Streams music from phones and tablets to the factory stereo without replacing the head unit.
• Separate volume control: Lets users adjust call volume and music volume independently using remote buttons.
• 3.5mm AUX input: Adds a wired auxiliary input to play MP3 players, iPods, Android phones or tablets if needed.
• Charging port: Provides a 5V 500mA charge output for a phone while in use, useful on long drives.

Who It's For

This adapter is best for drivers with Becker radios from roughly 1994 to 2002 who want a non-destructive way to add Bluetooth streaming and handsfree capability while keeping factory controls and steering wheel button functions. It suits owners who value an integrated look and do not want to replace the original stereo or alter wiring.

It is not for vehicles with incompatible Becker models such as certain Indianapolis or Monza units or Porsche CDR23 fiber optic systems, and users who require USB flash drive playback or higher USB charging current should look elsewhere.

Pros & Cons

Cons
