The NTG 4.7 firmware update is a critical maintenance step for Mercedes-Benz owners using the COMAND Online Gen 3 system (typically found in vehicles manufactured from June 2013 to 2015). While the hardware is nearly identical to NTG 4.5, the 4.7 firmware enables essential modern features like iPhone tethering (Bluetooth PAN) for internet access and faster system performance. Latest Update Information (2026)

As of early 2026, the most recent developments for the NTG 4.7 platform focus on map data and aftermarket integration rather than core OS overhauls:

Latest Map Version: The V25.5 (2025-2026) update for Europe and Turkey is currently available, ensuring navigation remains accurate for modern road layouts.

Firmware Status: Official factory firmware updates for this "legacy" system are typically only available through Mercedes-Benz dealerships or specialized independent shops using XENTRY Online. Key Benefits of Updating

Upgrading your NTG 4.7 system provides several functional advantages over older versions:

Enhanced Connectivity: Supports direct tethering for both iOS and Android devices, allowing for internet browsing and Mercedes-Benz apps.

System Fluidity: The 4.7 firmware includes a CPU speed boost and a larger internal SATA drive (upgraded from 80GB to 100GB), resulting in smoother menu transitions.

Visual Refinements: Updates the interface with modern red-line accents compared to the older brown/gray shades of NTG 4.5.

CarPlay Compatibility: A current firmware version is often a prerequisite for activating third-party CarPlay/Android Auto modules. How to Perform the Update

Depending on what you are updating, the process follows two main paths: 1. Official Map & Software Update

For standard navigation updates, you can use the official Mercedes-Benz Portal: Mercedes NTG 4.5/4.7 Maps Update | Navi World

This guide outlines the procedure for updating the Mercedes-Benz COMAND NTG 4.7

system. Updating NTG 4.7 typically involves two distinct components: a firmware update (system software) and a map update (navigation data). 1. Essential Prerequisites

Before starting, ensure you have the following hardware and information ready: Vehicle Identification Number (VIN) : Required to generate a unique activation PIN code Storage Media : A USB 2.0 stick or SD card with at least 64GB of space for a full regional update. Power Stability

: A stable battery is critical. For firmware flashing, professional guides like

recommend a 12V charger capable of delivering at least 50 Amps to prevent system bricking. File Formatting : The USB/SD card must be formatted to , depending on the specific update package requirements. 2. Updating Firmware (System Software)

Firmware updates for NTG 4.7 are typically not "DIY" friendly and usually require specialized diagnostic tools. : Requires a Vehicle Communication Interface (VCI)

and engineering software like Mercedes Xentry or DTS Monaco. NTG 47 Firmware Update: What You Need to

: Updates can improve system responsiveness, fix bugs, and are sometimes a prerequisite for enabling 3rd-party CarPlay/Android Auto

: Improper flashing can permanently damage the head unit. If you are not experienced with diagnostic tools, it is safer to consult a dealership or a specialist. Changes to the COMAND map - MID AUTO

For Mercedes-Benz COMAND NTG 4.7, firmware and map updates are handled differently. Firmware updates usually require dealer-specific diagnostic tools, while map updates can be performed manually at home using a USB stick and a license PIN.  Manual Map Update Procedure 

This is the most common "update" owners perform to get the latest road data (e.g., the 2022/2023 V20 versions for Europe or North America). 

Prepare Hardware: Use a 32GB or 64GB USB stick formatted to FAT32.

Obtain Files & PIN: Map files and a vehicle-specific Activation PIN (linked to your VIN) must be purchased from retailers like Navi-World or via eBay.

Transfer Data: Unzip the map files directly to the root of the USB drive (no folders). Install in Vehicle:

Start the engine to ensure constant power (the process takes 30–60 minutes).

Insert the USB into the car's slot. The system should automatically detect the update. Enter your unique Map PIN/License Key when prompted.

Wait for the progress bar to reach 100% and restart the system.  Firmware vs. Map Updates  NTG 4.7 Firmware version, and update!? : r/mercedes_benz

Updating the NTG 4.7 firmware (found in many Mercedes-Benz models from 2011–2015) is less about a single "download" and more about modernizing an older, reliable system. While newer Mercedes models use MBUX with over-the-air updates, the NTG 4.7 requires a manual touch. The "Why" Behind the Update Owners typically seek out this update for two main reasons:

Modern Features: The most popular reason is to enable third-party Apple CarPlay and Android Auto modules. These often require a specific firmware level to work seamlessly with factory steering wheel controls.

System Reliability: Updated firmware can fix issues with the factory Bluetooth chipset (often the CSR chipset), which can drop calls in areas with heavy signal interference. The Update Process

Updating the firmware is distinct from updating the navigation maps:

Firmware (Head Unit): This is usually performed by a dealer or a specialized technician using XENTRY software. It updates the core operating logic of the unit.

Navigation Maps: You can do this yourself. For 2026 driving, "V20" map updates are available via USB or SD card. You download the files, extract them to a FAT32-formatted USB, and insert it into the car.

The PIN Code: Most map updates since 2012 require a unique License (PIN) Key tied to your vehicle’s VIN. Troubleshooting & Common Hurdles

Hardware Limits: Cars produced after late 2015 may have different electronics that complicate dongle-based activations, sometimes requiring a full head-unit swap if you want "native" feel. Improved Navigation Performance : The update enhances the

Installation Blockage: If your current map version is extremely old, the hard drive might block a direct jump to the newest 2026 maps. In these rare cases, a technician must first delete the old map partition using XENTRY. Mercedes Comand NTG 4.5/4.7 North America V20 - Navi World

If you are looking for a review of the NTG 4.7 firmware update, it is often described by users as a "game-changer" for older Mercedes-Benz infotainment systems, primarily because it enables modern connectivity features that were previously unavailable. Key Performance Highlights

Enhanced Connectivity: The primary benefit is the ability to connect newer devices like the iPhone 5 and later via Wi-Fi for faster data streaming and internet browsing, a feature missing in the older NTG 4.5.

App Integration: The update unlocks several built-in Mercedes-Benz apps, including TuneIn Radio, weather, Google search, and news.

System Stability: Reviewers note that the firmware update can resolve common Bluetooth drops and improve Siri response times, with some users seeing response delays drop from 4 seconds to just 1.2 seconds.

Visual Interface: While mostly identical to the previous version, NTG 4.7 features a distinct red line at the bottom of the interface instead of the older brown shade. The "Update" Reality

Most users seeking this update are actually looking to bridge the gap to modern smartphone integration.

CarPlay & Android Auto: Official firmware updates alone do not add these features to NTG 4.7. Instead, many reviewers recommend using the firmware update as a foundation for 3rd-party plug-and-play modules from brands like Navi World or K-Tech Modules.

Map Updates: Firmware updates are often paired with the latest V20 map data, which users report takes approximately 1 hour and 45 minutes to install via a FAT32-formatted SD card or USB.
