🔍 Technical Insight Into the Problem

Mercedes-Benz NTG 4.5 and 4.7 head units are advanced multimedia systems that control everything from navigation and Bluetooth to climate and vehicle settings. Over time, internal components such as eMMC memory chips, voltage regulators, and logic controllers can fail due to excessive heat, voltage fluctuations, or aging hardware.

Unlike simple replacements, our service preserves your original configuration and VIN programming, saving you from post-install coding hassles at the dealership.
