Metra Electronics AXDI-MB1

The Metra Axxess AXDI-MB1 (often listed as METAXDI-MB1) is an advanced automotive radio replacement data interface module designed specifically for select Mercedes-Benz vehicles (spanning model years roughly 2001 to 2018), along with certain compatible commercial platforms like Dodge/Freightliner Sprinter vans.

When upgrading the factory head unit in modern European luxury vehicles, standard wiring harnesses fail because entertainment systems and dashboard signals operate through complex data-bus networks. The AXDI-MB1 serves as a translator, allowing you to install a modern aftermarket radio while maintaining critical electronic integration.

Key Product Features

• Data-Bus Integration: Translates factory data network signals to seamlessly support aftermarket radio installations without disrupting vehicle electronics.

• Provides Accessory Power: Generates a reliable 12-volt switched accessory power output, bypassing the lack of a traditional ignition wire behind the factory dash.

• Steering Wheel Control Support: Built with adaptability to retain factory steering wheel audio controls (often integrating directly with an Axxess control harness or module).

• Retains Essential Vehicle Settings: Preserves factory warning chimes, menu access, or parking sensor functions where applicable on supported trims.

• Micro-B USB Updatable: Allows firmware updates via computer to ensure compatibility with future vehicle configurations and radio head units.

Vehicle Compatibility

The AXDI-MB1 interface is engineered for a wide range of European platforms, predominantly:

• Mercedes-Benz: Select models manufactured between 2001 and 2018 (including various C-Class, E-Class, ML-Class, SLK, and GL platforms, depending on whether they feature standard audio configurations or specific CAN-bus setups).

• Dodge / Freightliner: Select commercial vans (such as the Sprinter) utilizing matching Mercedes-derived electrical architecture.
