Mercedes-Benz GLA Android Head Unit Review — Under $400 Upgrade

Upgrade Your Mercedes-Benz GLA X156 with a 12.6-Inch Android Head Unit

Considering an infotainment upgrade for your Mercedes-Benz GLA X156? A 12.6-inch Android All-in-One head unit, especially one powered by a Qualcomm Snapdragon CPU, can transform your driving experience, offering tablet-like functionality right in your dashboard. This review delves into the real-world benefits, installation process, and overall value of this popular CarPlay retrofit.

Before and After: A Dramatic Infotainment Overhaul

The factory infotainment system in the Mercedes-Benz GLA X156, while functional, often feels limited by its screen size and feature set. Upgrading to a 12.6-inch Android head unit provides a significant visual and functional improvement. The larger, high-resolution display offers a more immersive experience, making navigation, media playback, and app usage far more enjoyable. Models equipped with a Qualcomm Snapdragon processor ensure smooth multitasking and quick app loading times, eliminating the lag often associated with older systems. This Android Auto upgrade essentially turns your car's dashboard into a smart device, allowing you to install and use a wide array of applications from the Google Play Store, such as YouTube, Netflix, Spotify, and your preferred navigation apps like Waze or Google Maps.

Installation Process and Key Features

The installation of an Android head unit in a Mercedes-Benz GLA X156 is a detailed process that typically takes around 3 to 4 hours. Here’s a general overview:

1. Removal of Factory Unit: The existing OEM monitor and commander unit are carefully removed to avoid damage to the surrounding trim.
2. Wiring and Compatibility Check: New wiring harnesses are connected to integrate the Android head unit with the vehicle's systems. A crucial step involves testing compatibility, ensuring all essential functions communicate correctly.
3. Functionality Testing and Coding: Before final assembly, the unit undergoes rigorous testing. For Mercedes-Benz NTG 4.5 Command systems, this often includes activating the AUX function via coding. This allows the Android head unit's audio to be routed through the car's factory speaker system, providing superior sound quality.
4. Final Assembly and Testing: Once all functions, including navigation, Bluetooth, and Wi-Fi, are confirmed to be working perfectly, the new head unit is securely installed, and the dashboard is reassembled. A final check ensures a seamless fit and finish.

Beyond the core features, the ability to use Android Auto and Apple CarPlay wirelessly or via USB is a significant advantage. The integration with the vehicle's speakers, especially after AUX coding, enhances the audio experience, making music and calls clearer and richer. Durability is generally good for these units, provided they are installed correctly and high-quality components are used. Like any electronic device, regular software updates and avoiding excessive background app usage can help maintain optimal performance over the years. While specific warranty periods vary by manufacturer, reputable installers often provide after-sales support.

Is the Android Head Unit Upgrade Worth It?

For Mercedes-Benz GLA X156 owners seeking a modern, feature-rich infotainment system, the Android head unit upgrade is often considered a worthwhile investment. The ability to run familiar apps, enjoy a larger display, and benefit from enhanced connectivity provides a significant improvement over the stock system. The cost, typically starting around 400,000 Korean Won (approximately under $400 USD, depending on the specific model and features), makes it a relatively affordable way to modernize your vehicle. Additional costs may apply for features like AUX activation coding, usually ranging from 100,000 to 200,000 Korean Won (approx. $75-$150 USD). While the initial investment and installation time are factors, the enhanced daily driving experience, access to modern navigation and entertainment, and the overall aesthetic improvement often justify the expense for many owners.
