NTG6 Map Code
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.

Not sure which generation you have? Run the VIN 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. 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.
NTG6 map update — quick path
- Get your VIN and region. Both on the data card or service booklet.
- Create the USB using DLM. Pick NTG6, the correct region, the latest compatible map version.
- Insert the USB, start the navigation update from the menu, wait for the Map License Key prompt.
- Generate the NTG6 code below matching the version and region on screen.
NTG6 codes are manual. Our team generates them. Expect 20 minutes to 3 hours during GMT+2 hours per our 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 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.
In supported countries you can add the entitlement through the Mercedes Me app. 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. 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.
