Data Interface with SWC - Mercedes-Benz 2016-2021 — AXTC-MB3

This vehicle-specific interface from Axxess is designed for factory radio replacement, providing a complete solution to retain features that are typically lost during installation. Patented auto-detect technology automatically identifies the vehicle type, radio connection, and preset controls while enabling retention and dual-assignment of steering wheel controls. The interface provides connections for multimedia radios, including NAV outputs, accessory power, and a 12-volt illumination output, while preserving R.A.P., balance, and fade. Compatible with all major radio brands and suitable for both amplified and non-amplified systems, it can also be manually programmed for most vehicles and retains settings even after battery disconnection or interface removal.
