Researched compatibility

An independent parts catalog lists A2139009020 across multiple C-Class, E-Class, AMG E53 and G550 configurations, reinforcing the need for VIN-specific confirmation. A2139009020 application catalog.

Required equipment

This amplifier is intended for vehicles originally equipped with the compatible Burmester factory sound system, commonly associated with Mercedes option code 810.

It is not a plug-in upgrade for vehicles equipped with:

Standard or base audio
A different Burmester system generation
A different speaker configuration
An incompatible multimedia head unit
Different electrical or fiber-optic connectors

Programming notice

Professional installation and Mercedes-compatible programming should be expected. A replacement amplifier may require:

SCN coding or vehicle personalization
Software flashing or updating
MOST/fiber-optic network configuration
Variant coding for the vehicle’s speaker arrangement
Clearing component or communication faults

Mercedes parts guidance specifically states that the module must be checked for current flashware after installation. A used unit should therefore not be advertised as guaranteed plug-and-play.

Before purchasing, match the original part number and connectors, confirm option code 810, and verify compatibility using the complete 17-digit VIN.
