# NTG6 Map Code Canonical URL: https://mbretrofit.it/guides/map-code/ntg/ntg6 Description: Generate a VIN-validated NTG6 map activation code for Mercedes MBUX Gen 1 (W177 A-Class, W247 B-Class, W118 CLA, W167 GLE, W213 facelift). Region coverage and troubleshooting included. ## What is NTG6? NTG6 is the first generation of Mercedes-Benz MBUX, launched in 2018 with the W177 A-Class. It replaced the older COMAND NTG5.5 across the volume models from 2018 on. Also called MBUX Gen 1 or MBUX 1. What NTG6 brought over COMAND NTG5.5: * Touch-capable centre display, landscape on most models * "Hey Mercedes" voice assistant (first generation) * Two driver-configurable widgets and customizable home screens * Augmented-reality navigation on select models * Touchpad on the centre console replacing the old COMAND rotary dial Use this page if your MBUX Gen 1 car asks for a **Map License Key**, **Navi PIN**, **Activation Code**, or **PIN code** during a USB navigation update.

Run the [VIN lookup](/guides/car-lookup). It reads your data card and reports the NTG version. ## How to identify NTG6 in your Mercedes The fastest way is the [VIN lookup tool](/guides/car-lookup). Visual cues: * **Two horizontal screens side-by-side** behind one glass panel (instrument cluster + centre display) * **"Hey Mercedes" voice icon** in the bottom-left of the centre screen * **No rotary COMAND knob.** Only a touchpad on the centre console. ### VIN lookup An interactive vehicle lookup is available on the canonical guide page. ### Video tutorial A generation-specific video walkthrough is available on the canonical page. ## NTG6 map update — quick path 1. **Get your VIN and region.** Both on the data card or service booklet. 2. **Create the USB** using [DLM](/guides/map-code/dlm). Pick NTG6, the correct region, the latest compatible map version. 3. **Insert the USB**, start the navigation update from the menu, wait for the Map License Key prompt. 4. **Generate the NTG6 code below** matching the version and region on screen. Enter your VIN in the map-code flow to confirm the compatible navigation system, region, and version. > **NTG6 codes are manual.** Our team generates them. Expect 20 minutes to 3 hours during GMT+2 hours per our [Terms of Service](/terms-of-service). Code shows on this page and arrives by email. ## NTG6 region compatibility — important for imports NTG6 head units are region-locked at the factory. If your car region is Korea, Southeast Asia, or Japan (including parallel imports), and you want to install a different region's map (Europe, Africa / Middle East, North America), our service won't work. The car will reject the code regardless of how it was generated. To install a foreign-region map on an Asian-region NTG6 head unit, you have two options: * **Change the head unit region** through a specialist service. Search "Mercedes NTG6 region change". * **Replace the head unit** with one from the target region. Refunds aren't granted if you ignore this. We flag the constraint in the code-generation dialog and on this page. Check your region before buying. ## NTG6 common problems ### "USB stick is not valid" even though USB is correctly prepared Almost always a region mismatch. The USB region must match the head unit's factory region. The [VIN lookup](/guides/car-lookup) confirms your car's region from the data card. ### Navigation menu does not appear on the display The car is missing the navigation entitlement on Mercedes' side. A map code can't fix that. Without the entitlement, the navigation app is hidden. ![Missing navigation menu on NTG6 display](/ntg/navigation-ntg6.png) In supported countries you can add the entitlement through the [Mercedes Me app](https://www.mercedes-benz.co.uk/passengercars/buy/digital-extras-overview/apps/me-app.html). Buy the entitlement before buying a code. We can't refund codes for cars without it. If Mercedes Me doesn't offer the entitlement in your country, email [contact@mbretrofit.it](mailto:contact@mbretrofit.it). We'll check if a workshop activation is possible for your VIN. ### Update interrupts midway through install NTG6 maps run 8–15 GB. Install takes 45–75 minutes. Mid-install failures usually mean: * **Battery voltage dropping.** Keep the engine running or use a battery maintainer. * **USB stick going to sleep.** USB 3.0 stick from a reputable brand. * **Doors opening or keys removed.** The car reads these as cancel signals. ### "Map version not supported" — firmware too old NTG6 firmware caps the max map version. If the car rejects the newest map in DLM, your firmware is older than the map. Get a workshop firmware update or pick the previous map version DLM allows. ## NTG6 map coverage by country The complete country coverage is available on the canonical page. ## Frequently asked questions about NTG6 ### How long does the NTG6 map update take in the car? 45 to 75 minutes for a full region map. Keep the engine running or use a battery maintainer the whole time. ### Is the NTG6 map update free? The Mercedes dealer charges €250–€400 for an NTG6 map update. Through MBRetrofit Tools the code is a fraction of that. Same map license, just no dealer mark-up. ### My W177 A-Class — same process as W167 GLE? Yes. Every NTG6 model uses the same code-based activation. The prompt screen wording is identical across W177, W247, C118, H247, X247, W213 facelift, etc. ### What is the difference between NTG6 and NTG7? NTG6 (MBUX Gen 1, 2018+) has landscape side-by-side screens. NTG7 (MBUX Gen 2, 2020+) has a portrait tablet-style centre display. NTG7 starts with the W223 S-Class and rolls down the line-up. Both use the same activation-code mechanism for manual map updates. ### Can my imported Asian-market W177 install a European map? Not directly. NTG6 is region-locked at the factory. Region must be changed at a specialist workshop first, before any map code will be accepted.
