If you own an older Mercedes-Benz, you might have noticed that some of your car’s connected features have stopped working. This is likely due to the phasing out of 3G mobile networks. Major network providers are shutting down their 3G services to make way for faster, more advanced 4G and 5G technologies.
This guide will explain why this change is happening and walk you through the steps to upgrade your vehicle. By upgrading, you can restore and improve your car’s connectivity, ensuring you get the most out of your Mercedes-Benz for years to come.
Upgrading a Mercedes 3g to 4g upgrade is increasingly necessary because many regions are turning off 3G/UMTS networks. That means some connected services may stop working (remote lock/unlock, vehicle status via app, map updates, etc.).
Why are 3G networks being shut down?
Mobile networks are switching off their 3G services to free up resources for newer 4G and 5G networks. These advanced networks offer greater speed, capacity, and efficiency. For owners of older Mercedes-Benz models, this “3G sunset” means the communication module in your car, which relies on the 3G network, can no longer connect to services like mbrace®, emergency calls, and remote vehicle access. Without an upgrade, these features will become unavailable, affecting both convenience and safety.
The benefits of a 4G upgrade
Moving to 4G brings your vehicle’s technology up to date. The most noticeable improvement is faster and more reliable connectivity. This means quicker data transfer for all your car’s online services.
With a 4G connection, you’ll regain access to modern infotainment features, including music streaming and in-car Wi-Fi. Navigation systems will benefit from faster real-time traffic updates, helping you find the best routes and avoid delays. Fundamentally, upgrading to 4G ensures that your vehicle’s smart features continue to function as intended.
The upgrade process
Upgrading your Mercedes-Benz to 4G involves replacing the old 3G communication module with a newer 4G-compatible one. This is typically a job for a professional. You can book an appointment with an authorised Mercedes-Benz dealership or a specialist automotive electronics installer. They have the correct tools and diagnostic equipment to perform the installation and integrate the new module with your car’s existing systems.
The cost of the upgrade can vary depending on your vehicle’s model and year. Some dealerships may offer specific upgrade packages, so it is a good idea to contact your local service centre to get a precise quote.
Choosing the right option
When looking into a 4G upgrade, you will find several options available. Authorised Mercedes-Benz service centres offer official upgrade paths that guarantee compatibility and come with a warranty. There are also third-party solutions that might offer different features or come at a lower price point.
When comparing options, consider the features offered, the warranty provided, and the reputation of the installer. For most owners, the dealership route provides peace of mind, knowing that the work is carried out by trained technicians using genuine parts.
Troubleshooting potential issues
After an upgrade, you might encounter some minor issues. If your connectivity seems intermittent or certain features aren’t working, the first step is to restart your vehicle’s infotainment system. If the problem persists, contact the installer who performed the upgrade. Compatibility issues between the new module and older vehicle software can sometimes occur, but these can often be resolved with a software update.
Future-proof your Mercedes-Benz
Upgrading to 4G is more than just a fix for the 3G shutdown; it’s an investment in your vehicle’s future. With a modern communication module, your car will be prepared for future technological advancements. This not only improves your driving experience now but also helps maintain your vehicle’s value over the long term.
Time to make the switch
The shutdown of 3G networks has a direct impact on the connected services in many older Mercedes-Benz models. Upgrading to 4G is the clear solution to restore these features and enhance your vehicle’s capabilities. It provides faster connectivity, access to modern services, and prepares your car for the future. Contact your local Mercedes-Benz dealer to discuss your options and schedule your upgrade.
