Mercedes-Benz E-Class W212 Android Head Unit Review

Revitalizing Your Mercedes-Benz E-Class W212 with an Android Head Unit

Many owners of the Mercedes-Benz E-Class W212, particularly models like the E220 from around 2015, face common issues with their aging infotainment systems. This can range from a completely blacked-out monitor to malfunctioning components like the High-Pass filter (often integrated into toll transponders) and the dashcam. When these problems arise, a comprehensive solution is needed. This review details a real-world case where an owner in Busan, South Korea, opted for a full infotainment upgrade, replacing the original NTG4500 navigation system with a modern Android all-in-one unit. This not only resolved critical system failures but also brought the car's technology into the 21st century.

Addressing System Failures and Upgrading the Infotainment

The owner of this 2015 Mercedes-Benz E-Class W212 presented with a critical situation: the main display was blacked out, rendering the backup camera useless, and both the High-Pass unit and the dashcam had ceased functioning. These combined issues created a significant inconvenience and safety concern. The team at 'Today's Car' in Busan meticulously diagnosed each problem, clearly explaining the faults to the owner with photographic and video evidence. Before proceeding with the upgrade, the existing NTG4500 navigation system was carefully removed to ensure no damage to the vehicle's wiring or internal components. This careful dismantling is crucial for the stable integration of the new system.

Following the removal of the old system, the new Android all-in-one head unit was installed. The transformation was striking, giving the E-Class a modern aesthetic akin to newer vehicles. For a clean look and enhanced usability, the USB and SIM card slots were discreetly integrated into the glove compartment. To enable the full functionality of the Android head unit, internet connectivity is essential. The owner was guided through connecting to a Wi-Fi hotspot or installing a SIM card. Once connected, the system allows for seamless integration of various apps, including streaming services like YouTube, and navigation apps, significantly enhancing the driving experience.

Installation Process: From Old to New

The process of upgrading the Mercedes-Benz E-Class W212's infotainment system involves several key steps to ensure a seamless and functional result:

1. System Diagnosis and Removal: The existing navigation system and any malfunctioning components (like the High-Pass unit or dashcam) are thoroughly inspected and then carefully removed without causing damage to the vehicle's original wiring or interior.
2. Preparation and Wiring: The space is prepared for the new unit, and any necessary wiring harnesses or adapters are connected to ensure compatibility with the E-Class W212's electrical system.
3. Android Head Unit Installation: The new Android all-in-one unit is physically installed into the dashboard, ensuring a flush and integrated fit.
4. Connectivity Setup: The unit is connected to the vehicle's power and any required data sources (Wi-Fi or SIM card). The owner is then guided through initial setup, including account synchronization and app installation.
5. Testing and Finalization: All functions of the new head unit, including touch screen responsiveness, audio output, navigation, and connected apps, are tested to ensure everything operates correctly.

The entire process, including the replacement of the monitor, High-Pass unit, and dashcam, took approximately 3 to 4 hours at the 'Today's Car' Busan branch. The cost for such an upgrade typically starts in the range of 500,000 Korean Won (approximately $370 USD, subject to exchange rate fluctuations), but can vary based on the specific Android head unit model chosen, the complexity of the installation, and any additional features required.
